How could Uber possibly be described as a monopoly when they have multiple competitions in every market they operate in?

I was refining the posters "natural" language.

The VCs fund these projects are going after monopolies, not some capitalist delusion about "best" outcomes.

It's clarifying: Facebook isn't the "best" social platform, it simply became big enough to box out competition.

This is why corporations are allowed to operate at a loss.
