That is not at all what I am implying. When you buy
that much amount of land, which is a basic human necessity, at minimum the public needs to know what the plans are for those lands, right? If someone buys 5 acres of land, that is a different story, nobody cares. The scale is what making the difference here.
Let me ask you another question - recently (2019 I think), Bill bought 14,500 acres of land for 171M in a single deal. 171M is pocket change for Bill. According to your logic, he can continue to buy farmlands across the country (because "freedom") with nobody asking any questions. What happens if he ends up owning half (or 75% or whatever) of all available farmlands? You want one single man to control your food supply?
He can buy all the Ferraris/Picassos/megayachts etc on the planet, that would make zero difference to anyone (except maybe other billionaires). It is when he starts buying water sources, land etc it becomes a problem. It has nothing to do with dictatorship.
