well i don't want to speak for everyone's government but just about anywhere I have ever been when something looked like it was going to be even a little bit popular it would end up overdeveloped very quickly until it was basically ruined... this goes for any industry as well. If it is determined that a part of town can support a couple of coffee shops or a massage shop you can bet your bottom dollar that the masses are going to put so many of these things in that area that none of them can survive any longer.
