Skip to 06:53:45, where he talks about it, and his stance on selling houses for profit.
I think you are just deluded about it at this point.
And be careful, you might find some reports coming your way, especially since you have admitted to paying people 30x the housing price for them to relocate their housing plot, right here on the forums.
