Additionally, home-ownership has the unique feature to be financed with money which would otherwise be a sunken cost.

I like the idea of some kind of modern/virtual self-sustained living, where you own your house, produce your own energy and cover all costs by dividends from stocks of the same companies you buy products from.

A home is a massively illiquid and spectacularly undiversified asset, and the same benefits can be gained by, say, investing in a spread-out housing cooperative with a diverse set of owners.

Ownership by the workers of the means of production and distribution! ;)

Yep, but actual ownership of a share with the choice on what to own on top of a capitalist base, not forced ownership together with everyone else through a state with corrupt elites.
