Time and again we see the claim that Uber is a taxi company, despite the obvious differences between Uber and traditional taxi companies. What you are saying is that the differences between taxis and Uber are inconsequential and irrelevant, hence "Uber drivers are taxi drivers".
You are entitled to your opinion about the differences between Uber and taxis, but that doesn't mean that everyone has to agree with you. I find the differences between Uber and taxis to be both relevant and consequential, so I believe that Uber drivers are NOT taxi drivers.
As for Uber being a monopoly, I fear that you have not really looked closely enough into the market that Uber serves. There is significant competition to Uber, and if Uber falters in its remarkable record of satisfying its customers, its competitors will swoop in to claim its market share.
