Just to play devils advocate; making everything in a town 5 acre min is a terrible move from a city/town infrastructure. It decreases the ability to hook up multiple homes on utilities, increases the lane miles of roads to provide service, ect. You can also make an argument that it decreases the overall available land for property owners. Say a small rural ag parcel sells, that's 50 acres; with that kinda rule, you pretty garantee it will be 10 5 acres pieces, each too small foe productive use; instead of maybe 2 20 acre pieces, and 10 1 acre pieces.
