As for the second - the concerns you brought up are exactly why we need a more socialistic distribution of wealth. Either people have to work for wages too low to live on, or they're replaced by robots. The problem is, when they are replaced, they don't get the wealth that the robot generated - that all goes to the owner. This is why UBI will probably be a necessity - most people don't need to work to produce all of society's goods and services nowadays.
I'd say that exclusively controlling infrastructure for high prices without competition is pretty aggressive and needs regulation too
