The problems you are describing are not caused by free market capitalsim but statist interventionism.
Well, I would add certain types of monopolies.
But yea, "people who guard and regulate the system" ... good job on the "free market". You'd need to twist language by a lot to make that work.
At the mention of AIs in the OP: be happy if humans can keep a 1% share in replicating mass. Our society consists of huge farms, houses, vehicles, computers, networks, streets and railroads, tools, data storage from books to SSDs... and a share of humans that pushes the buttons and is flexible in fixing things. If an alien species came to see us, that famous image of two naked humans would be little more than a symbol for our civilization. They might need a second look to even recognize us; when would they ever see a human with no clothes, no tools, no accessories, no vehicle or building?
And where's the difference from inventing a hoe to inventing a calculator? The job of manual calculation is gone for humans, fast silicon circuits do it now. Have fun trying to dig up farmland with bare hands.
