You should live in a country without a culture and legal framework for competitive markets, or try to talk to someone first hand who has such experience. I suspect you're a good person who just misunderstands how markets and individual rights interconnect.
If the local government can simply declare "there are enough X, no more are allowed" then the rich, powerful and well-connected elite can solidify their privileged positions forever. Raise prices, lower wages, provide poor service - it doesn't matter, their buddies on the city council will guarantee no one is allowed to open a competing business.
If you want to protect the lower class and middle class, you don't want to hand the elite a tool to turn their business into a local monopoly for the price of a campaign contribution.
