You make a great point about services like Uber, etc. For this reason alone, I now think cities need to stop with the bans and such. Cabs are not a substitute as no one likes to wait hours or walk miles or both in hope of catching one, a situation that's quite common in places like San Francisco (especially at night) and I imagine, many other cities.
