There are plenty of examples in the article that you are skipping over. First of all, getting that health certificate you mention takes several months. And you need one for every employee. In a brick and mortar, you only need one, period. And you need to get your cart or truck cleaned at a specially licensed "commissary" every morning. Then you have the case of this lady: She had a street-vendor’s license, she said, but didn't understand that she also needed a separate permit for her cart. This whole situation with licenses costing money and being "leased", plus the commissaries, reminds me of the Boston cab situation right now - when you need to pay a bribe to be able to driver a cab for the day, regulation is definitely getting in the way.
