I just wanted to point out that so long as a restriction is legal, a seller of land can place use restrictions or obligations that bind future parties. It is called a covenant running with the land and must be recorded so thst it shows up if someone does a title search.
Easements are a common one and in the past covenants were also sometimes used for horrible purposes such as preventing sales to Jews or POC. Those types of covenants aren’t enforceable of course anymore but were until relatively recently. Land is often sold with a covenant that requires it to be kept undeveloped for example especially when the sales price reflects that kind of restriction.
