Money is only a bookkeeping tool for complex societies. The aim of the owner class in a worker-less world would be accumulation of important resources to improve their lives and to trade with other owners (money would likely still be used for bookkeeping here). A wealthy resource-owner might strive to maintain a large zone of land, defended by AI weaponry, that contains various industrial/agricultural facilities producing goods and services via AI.
They would use some of the goods/services produced themselves, and also trade with other owners to live happy lives with everything they need, no workers involved.
Non-owners may let the jobless working class inhabit unwanted land, until they change their minds.
