I think even landownership is not a problem, the problem is that people think about housing as an investment and not a tool(eg car).

Given the need for extensive labour and planning to construct most dwellings, how do you propose doing a built property from retaining value?

It served its purpose when the colony was being consolidated, but now that society has matured, this ownership has indeed to be reviewed if it is hindering society development. It will put some privileges in jeopardy, and some will not be all too happy about it.

I think that is going too far - we have seen the teaming mass of nothing in Ireland historically and well every precarious third world country where building a better proper cabin instead of a shanty shack will get it seized.

Landownership is not without flaws and reform potential but lets not go crazy here. Eminent domain already exists dor hindering development issues and shows why it is used sparingly.

Nah it was chattel slavery.
