You make a good point that the value of regulations for Uber is negligible. Regulatory capture is an understandable motivation by industry but its weird to see the public embrace it. I see a lot of people in this thread complaining about how Uber, AirBNB, and Turo aren't fair to industry. The point of regulation is to protect the public. If they aren't needed for that purpose they should be repealed for existing players. Taxi Medallions artificially constraining the supply of taxis were always a stupid idea regardless of whether Uber and Lyft were created.
Give someone a ride, let them borrow your car, let them stay over at your house while they're on vacatin, have a one night stand with them. Nobody thinks we need government regulations for this stuff. What is it about commerce that scares us so much?
