Forcing people to share large tracts of land is just as bad as forcing people to live close together in villages while leaving the land open. Just my opinion. Personally, I like elbow room.
I attended a public meeting a couple of years ago where our county was considering consolidating a large sprawling subdivision of 1 acre lots near me, forcing people to move together, making a loosely made village. The vacated land would resort to county ownership and stay permanently non-residential use. The public was up in arms! The meeting hall was packed with angry residents, with half the attendees not fitting into the building, but spilling out into the parking lot. The county officials called all the
local police in to maintain the peace ( an angry but non-violent peace). I was surprised not by the crowd, but by the number of police. I didn't know that we had so many in my rural community.
People live where they can afford to live and where they are comfortable to live. I would prefer to live on 100 acres but I can't afford it. So I live on 20. I have in the past lived in close housing areas and row homes. I hate the close quarters and it caused lots of unhappy stress. I am far happier with lots of land. My brother is the opposite. Sprawling land around him makes him apprehensive. He's happier in his close condo housing area. To each their own.
While it may appear that there is a shortage of land, I interpret it as a shortage of cheap land in desirable areas that are close to all the preferred infrastructure. The land is there, though no necessarily affordable to most people. Desirable land is priced accordingly (expensive), while undesirable land is too (cheap). Requiring co-habitation of large land parcels won't make it any more affordable. The United States has lots of vacant or open land, available for private ownership or leasehold. Other countries have far less, such as the United Kingdom. I have no
experience in other countries. But I suspect that land is there if you can afford it. It may not be exactly what you want in your dreams, but it is there.
I, for one, would not want to be forced by regulation to a limited amount of land.
Besides, who's to say just how much land a person needs? If you're an herb grower, should you be limited to 5 acres? If you're a vegetable grower, should the limit be 20? If you have a goat
dairy, are you allowed more land? If you are raising grass fed
beef, then could you have 200 acres or more? And on the opposite, if you raise nothing, should you be confined to an apartment or condo? Sticky questions.
