Of course vested interests in old industries will do whatever they can to block innovation. We're seeing it with all major industry disruptions. It used to be enough for the vested interests to write laws to block out, limit, or otherwise hinder additional traditional competitors (taxi medallions, ridiculous license requirements for florists[1], etc).

You can believe that there are valid reasons to regulate cabs and black cars, or you can not believe that. But it's intellectually dishonest to lump that question in with franchise laws and licenses for florists.
