Again same problem with PoW and PoS. If an entity holds a majority of coins it can blackmail the market. It doesn't matter if more (=substantially more) coins can be created (nota bene at a decreasing rate and therefore slowly) in the far future.
The overwhelming majority might never feel the need to mine, but knowing that they can if they want to without permission, makes all the difference between PoW and PoS.
No, it doesn't. Very weak opium of the people, nobody's gonna fall for that.

And if the worst comes to the worst for one of them copy the code and start from scratch.
