OK, but why just the land? Trusts hold stock, too, that some long-dead person bought. Their heirs receive the dividends from that stock, for not having done anything whatsoever. By your logic, why should that not be taxed?
What is so magical about land, that only that should be taxed? What makes it different from all other assets?

Yes, I recall the data on how concentrated stock ownership is. The exact same logic you are using on land tax applies to stock ownership. So... what was your point?
