Everything has or might have a risk. For all we know carrots increase the risk of cancer.

If we banned everything that increases the risk of some sort of bad thing we'd probably end up banning everything (or more realistically, everything we'd do studies on).

No, the symmetry of "anything could be dangerous" is broken by reality, by what is actually dangerous. Arguments of the form "all things look the same if you ignore all their differences" don't work.

Uh... I think you're assuming all your readers have the same precise understanding of "actually dangerous" that you do.

Is walking "actually dangerous"? Is cycling? Is driving? Is swimming? Is hang gliding? Different people will give different answers to these questions and I've even kept them all to the domain of transportation!

Once you get to the realm of all chemistry things get very murky. E.g. Is sugar dangerous?

In practice we're evolved creatures full of hacks that work well enough to mostly not die before we've had kids, I would be very surprised if there was a single substance we consume (both intentionally and not) that doesn't damage something.
