Cities are actually 'greener' if you look at things on a global scale, rather than just having few trees outside that a few species (deer, say) have somewhat adapted to living in the urban/wildland interface.

If everyone lived on 3 acres, you know how much truly wild land would be paved over?

Now, I strongly agree that people ought to have the right to purchase and live on a large lot if they want. Great, you earned it, have fun!

Requiring that? That's using the government to perpetuate a sprawly, carbon-intensive lifestyle that very much does exclude those who are not wealthy enough to purchase that much land. That's part of the point in many places with that kind of regulation.

The majority of residents of an area using the government to control that area is the pinnacle of democracy.

Actually, no there's plenty of land in America. Nothing would be paved, it would just be moved to yards (hint yards aren't paved). And if the population doesn't grow, then there's no reason America can't live like that forever.

When excluding illegal immigration, the US population is actually shrinking. There's no need to artificially box ourselves in.

7.7b people. https://www.census.gov/popclock/world

15.77b acres of habitable land. http://www.zo.utexas.edu/courses/THOC/land.html

15.77 / 7.7 = 2.04

Every human could have about 2 acres. At this level of distribution humans would essentially live in wilderness and integrate with nature. Oftentimes humans live in family groups so the actual point distribution would be uneven.

Unfortunately arable land needed to feed the humans varies by locale but tops at about .6 hectacres [0] or 1.48 acres[1]. This means that effective wilderness could be slightly less than .5 acres per human after some nominal usage for housing and utility right of ways.

> integrate with nature

That's false though. There are a lot of animals that do not want to be anywhere near humans, roads, houses or anything else. The presence of people wrecks it for them. Not to mention the jacked up carbon emissions if everyone had to drive around for everything because everyone is spread out.

Yes, there is some spatial optimization needed insofar as one would likely not want to be two acres in linear distance away from one’s infant. The habitable surface allocation could be thought of as virtual and fractional which would also account for point differences in relative value such as a natural spring, naturally occurring commodities like a gold mine or the human interest in subjective value like Hawaiian beachfront, all of which may change over time. Along the line of subjective preference is overall inter-human proximity in which some might choose higher or lower depending on intended lifestyle.

Human-avoiding life already has a hard time. The habitable surface estimate did not include many areas where the remaining ones exist, such as tundra, ice pack, mountains and deserts. Additionally inter-human proximity preference distribution will allow for additional area outside the aforementioned surface classifications.
