It seems to me that receiving a piece of land could be a liability. Some probably likes the freedom to choose where they live. Thus receiving money that one uses to pay rent is better than receiving by lottery a piece of land in the middle of nowhere. Some pieces of land live under municipal/regional rules that forces the user to take care of it in some way (build, prune trees, etc.)

An option to choose UB land or UB income when reaching 18yo might be an interesting compromise.
