There is a difference between banning and regulating. If a certain culture finds that certain businesses better be regulated for whatever reason (and your exsmple is actually a good one) that's OK and must be followed.

Take for instance the FDA that heavily heavily regulates the US market. I could argue that I as a customer should be able to choose myself what I eat and drink, yet that's not the case.

You may call that cartel, mafia, whatever you want but it's how administrations work..
