I think you might be focusing on the wrong thing here. There is no reason to outlaw ride shares, only ride shares that engage in illegal lobbying, labor violations, and disregarding of the law. In fact this is not specific for ride share companies, but companies in general (including traditional taxi cab companies).
People have been complaining about Uber not because it is a ride share company that undercuts the traditional taxi cab companies, but because they exploit their workers, bribe their elected officials, brake their local laws, and use VC funding to undercut their competitions. For this they should be outlawed.
