"Non-capital-owners will live on the largesse of capital, or will not live at all."
That's been tried several times now and has a tendency to end very badly for capital. You'd think folks with even a grade school level of historical literacy would know better than to stick a fork in that outlet.
It's never been tried before. Capital always required human labor, to be productive. Capital has never closed in on the ability to operate, maintain, defend, and expand itself without human assistance, as it is closing in on that ability now.
