I think that's really unimaginative and not thinking about it right. If you control the basic resources and own the tools needed to convert those into whatever you want, why does the "economy" even matter? If you can get anything you want without needing anything from the other 95% of people, having "consumers" in the sense you're thinking doesn't matter any more.
