How about an ownerless house that keeps its own rent money? An ownerless McDonald's franchise? Ownership is not just about money. Driverless cars don't really change anything about the concept of ownership. If you think driverless taxis are such a great idea and you want them to be operated in a non-greedy way, start a non-profit, or start a corporation and make it public so that anyone who wants can invest and share…
Several authors have written about algorithmically generated & operated companies or entities (Charlie Stross, the Ghost in the Shell) either as litigation shields or entities which outlived their owners but continued to operate.
The idea is certainly odd, to essentially create autonomous and roughly speaking self-sufficient/directed artificial creatures, but it's consistent at least.
The thought that makes me saddest i think is just that the core quality we'd imbue humanity's first autonomous creations with would be capitalist wage-slavery (a literal non-hyperbolic one in this case).
