I am not "pretending" that it creates positive surplus value. It does create surplus value through simple mechanisms.

Also, it's unfair to say I am ignoring every single negative externality. All I did was challenge the questionable claim that Uber has much to do with the state of our cities being car-centric and underprovisioned by public transport, because the root cause of that situation is homeowners, not Uber. I didn't give my blessing to all of Uber's practices.

Putting aside the false analogy to child labor, I don't accept the framing that all low wage labor is uncool. It's a type of mindless compassion that can actually lead to anti-utilitarian outcomes in practice. Although I have no positive or negative judgment of Uber in particular regarding this point, because I haven't looked into it for Uber. https://news.ycombinator.com/item?id=32627174

Many cities and their suburbs were car-centric before Uber and many will be car-centric after Uber. Perhaps somewhat fewer will feel the need to own a car (or a second car) but that doesn't really change the basic nature of transportation options. If anything, there's probably been a (little) bit more attention paid to public transit and things like bike lanes in some cities during the period Uber has existed. Many of us use Uber or Lyft once in a blue moon. My life wouldn't change one iota if Uber vanished tomorrow.
