Earlier quoted context omitted.
Just because some people are willing to pay for something, doesn't mean it's right. People in general are very happy to pay for things that have huge externalities not directly affecting them.
What externalities for uber are you referring to?
Either the pedestrian is ruined for life, or society has to pick up the bill.
That's one of the clearest examples of externality you will ever see.
Our free choice evangelists try to frame the whole issue as "one Uber driver, one satified customer who only exercised a choice, and no one else exist in the world".
It's dishonest, but that's Internet discussions.
