But as Uber itself shows, the fact that a licensing system exists doesn't mean that all services are compliant. So you already can't assume everything is safe - you're just self-deceiving yourself into a sense of false security.

Yeah, obviously nobody can ever fully drop their defenses, nor totally disclaim personal liability.

In all the examples above, there's still room/need to stop aberrant behavior, eg, "why is this water so cloudy?! maybe I shouldn't drink it!"
