These are not fair comments because everything you say the taxi industry it replaced is guilt of and closing the market. Uber puts new cars on the road and opens the industry to those who are locked out.
Suppose taxi industry is guilty of murder, does that mean I can now commit murder too?
If it gets replaced by a strictly less murderous alternative, this alternative is preferable.
No, but if a taxi industry is murdering people, and also helped create laws that prevent competitors from entering the market, I think it is OK to get around the laws that prevent competitors from competing with the taxi murder mafia.
In this metaphor, "murder" stands for "operating a taxi service without the approval of the existing taxi services."
