Regardless, it is clear and well-evidenced that prohibition encourages a black market.
I did not deny that at all.
My point was- It does not always look like what happened in the US.
There are degrees of black market. We prohibit purchasing antibiotics without prescription and there is a black market for that. But its about whether or not we deem a particular resupt acceptable or not.
That calculation will change, item by item and population by population.
Prohibiting guns works well in many places for example. Perhaps it would not work so well in others.
My experience of drinking in Dubai is that you just go to a hotel and get shitfaced.
My experience in parts of Egypt (outside Cairo) is that it was nowhere near worth the effort and risk for the couple of cans that I was promised.
