Given the extremely wide evidence basis from existing data (there's millions of worldwide users) I'd argue no more than has been, and that the current data is sufficient to show its lack of effectiveness without any additional effort. But had the obviously-silly hypothesis (adding a tiny bit of something bad can have a good effect) been rejected from the start in a different context we'd never have gotten vaccines (which originate from a similar hypothesis in a different context).
The problem with homeopathy is not that it's a crazy idea. It's that it's been extensively shown not to work and is still being pushed as a good idea.
> It's that it's been extensively shown not to work
This is going off-topic, but I really think it depends on your definition of "not to work".
If people essentially throw in low-cost placebos to cure themselves of headaches and other minor ailments, while believing that this is exactly what they need, I consider this a net-positive for society compared to giving them actual medication that costs more with potential side-effects/harms.
Obviously, the fun ends when quacks prescribe homeopathy for serious stuff that needs actual treatment (in Germany, there was a case a few years ago where such a quack tried to treat his wife's breast cancer - obviously, this is beyond what should be legal). But for minor things that aren't too big of an issue even if left untreated, letting people use homeopathy if they're into that - why not.
It is also known, that placebos work better, if people believe; they are medicine.
Thats why Homeopathy "works"
"in Germany, there was a case a few years ago where such a quack tried to treat his wife's breast cancer - obviously, this is beyond what should be legal). "
But this, I see actually different. People of clear mind, should have any right to choose their treatment of choice. So informing them on the best options, yes! Telling them of the mechanism of fraudsters who prey on peoples hopes, yes!
But in the end maybe not forbidding them if they choose - for whatever reason - less standard methods.
Maybe the placebo works in their case. Maybe the alternative treatment with the roots of plant X had by chance an actual unknown effective drug in it. Who knows. But I know that telling people to follow standards is not allways the best way.
Btw. because if a recent case I know there are homeophatic cancer clinics in germany. So it seems to be legal?
I know of other alternative cancer treatment by the very weird "Dr. Hamer" who cannot be practised in germany if the patient actually has cancer. And I think this is not helping to disprove scams. (because I know people who are into it)

In theory, I agree with you. People should be clearly told "there is evidence that X works, and there is no evidence that Y works, however you are free to try Y at your own risk". And then they would make their choice.
But I am afraid that it wouldn't work so well in practice. First, there is the problem of who is this authoritative voice that tells people "X works, Y does not". Is it government? (Will it not become subject of political fighting? Like, depending on who wins the election, evolution either exists or does not exist, masks either help or do not help against COVID, etc.) Or is it some professional organization of experts? Then the fraudsters will make their own alternative organizations, that for a layman will look exactly the same. -- At the end, the layman has no idea whom to trust.
Second, the fraudster talking to you can be more persuasive than a website you read, simply because they can adapt their argument to your knowledge. Even if the website says "X works, Y does not", the fraudster can explain like "by 'Y does not work' they actually refer to Y1, but what I am selling is Y2 which is not the same thing", and there will be no one there to say "actually, Y refers to both Y1 and Y2" or "Y2 is just Y1 under a new name". For a layman it is difficult to evaluate when two things are or are not the same.
So at the end, either fraud is legal, or illegal. "Legal, but you have been warned, so use your best judgment" does not work for people with average intelligence and average expertise.
"First, there is the problem of who is this authoritative voice that tells people "X works, Y does not""
Isn't that a problem with your solution?
"So at the end, either fraud is legal, or illegal"
(In my scenario common doctors tell people of the treatments.)
Also, people offering alternative treatment are often very convinced that they are offering indeed the superior solution and the others are commiting fraud.
It is not that simple. We already have a replication crisis; some data out there is wrong, possibly the one that refute some wild idea.
In the ideal world, everything would be replicated and retested at least a few times. Practically, we do not have the resources, and sometimes other interests come into play. For example, those of some industry to fund studies that refute some wild idea that threatens their business. How many studies on safety of sugar are paid by Coca Cola?
We do have a replication crisis. But what you're saying is that because we have a replication crisis all prior data about basically everything is moot. As far as I know the replication crisis is most predominant in psycology and social sciences. In biology the replication crisis a bit more interesting, and while it needs addressing, it's fair to say that homeopathy seems to have been reasonably thoroughly debunked. However, in the spirit of exactly what I said above, never say never. If someone proposes a new type of experiment that can explore the homeopathy hypothesis further, that should definitely be at least slightly encouraged. The question is, what experiment DO YOU want to do? Double blind control trial? More basic than that, at the molecular level!
> . But what you're saying is that because we have a replication crisis all prior data about basically everything is moot.
That was not my intention. My intention was to say that a single study might not be good enough as a refutation. BTW one of the largest proponents of re-checking studies that were once considered reliable is a medical doctor, John Ioannidis. It is not just soft science that suffers from the problem.
Given that we are really short on money (and, with regard to ideas, always will be - it is cheaper to produce ideas than to test them even cursorily, much less thoroughly), every proposed mechanism will have large downsides. I do not have a proposal.
Homeopathy hasn’t been proven to not work in cancer. I mean, there is no double blinded randomized trial of say healing crystals. Should we still fund such a trial? I mean, there is no data to refute it.
The problem with homeopathy is not that it's a crazy idea. It's that it's been extensively shown not to work and is still being pushed as a good idea.
