That's clearly a bad argument. That's equivalent to saying that driving cars or flying planes should be available to everyone, without a driver's licence or pilot's license.

Don't strawman what I said. I didn't say psychedelics should be banned. I said that they shouldn't be sold in gas stations (aka easily available to the public).

I fail to see how that prevents prescriptions from being a viable option, or a "mdma license" similar to a driver's license that is issued only after a person proves that they can safely use it.
