Techno-feudalism and the rise of AGI: A future without economic rights?

Is a future where AI replaces most human labor rendered impossible by the following consideration:

-- In such a future, people will have minimal income (possibly some UBI) and therefore there will be few who can afford the products and services generated by AI

-- Therefore the AI generates greatly reduced wealth

-- Therefore there’s greatly reduced wealth to pay for the AI

-- …rendering such a future impossible

no the AI doesn't actually need to interact with world economy it just needs to be capable of self-substence by providing energy and material usage. But when AI takes off completely it can vertically integrate with the supply of energy and material.

wealth is not a thing in itself, it's a representation of value and purchasing power. It will create its own economy when it is able to mine material and automate energy generation.
