Or maybe I'm talking through my hat.
My intimate knowledge of UK land prices, policies, and patterns comes from some friends who, in the late 60s, bought a farm well away from everyone to get away from everyone only to wake-up and find themselves surrounded by housing developments lo these many years later.
Not happy they are.
Wishing to leave, they do.
Be damned if they'll sell out to Yet Another Developer to rape the countryside, they declare.
