Willy has no interest in the rights of property "owners" notice his concern that a landlord/investor does not pay taxes but a renter does. He hates investors, property owners and landlords with a passion and figures they should be taxed by the Federal government for the land they own.
Read what he has actually written, the NRST does not tax owners, it can't as that would be a violation of the Constitution. I does however levy a tax on commercial activities and is paid by the "customer" not the owner and seller.
That's partly how the corrupt, ruling-elite PRI keep the peons in economic slavery.
