It also makes doing your homework a lot harder. If I want to buy alcohol, I can go to a shop and can get something that’s correctly labeled with an alcohol percentage and is highly unlikely to contain methanol.

If I go buy some psychedelic, chances are it is diluted or laced, so I would have to know how to test that what they sell me is what I asked for.

There are jurisdictions where it's legal, and shops that will ship it virtually anywhere. The product is pure, tested, and consistent.

Of course you have to find such a shop (hint: try Canada), and it's still a lot of hassle for something that should be perfectly legal, and is, in many places.
