I lived in a condo that had thick stone walls built after WW2
It was still shit and I will do everything in my life to never have to live in these giant human hutches.
My house is right next to an actual forest. I can hop out of my vegetable garden and be hiking on a moment’s notice.
The holes in your logic are the individualism and scale. Very few people will ever be able to live in a detached house like yours, by definition. Either the forest will eventually be cut (rendering the nature dead), or the supply will forever be small and expensive (not accessible to millions of masses). The only way millions of people could have access to a large natural area to hike is indeed apartment blocks urban islands surrounded by large spaces of nature, like the 2nd image. They don’t have to have tens of floors, just 5 floors of large apartments can house many people with comfort while also having amenities (that can be paid sustainably too) to boost.
Bullshit. Once you’ve built your giant rabbit hutches for human, you’re going to need all the accompanying services these giant misery factories need. Industrial scale services for industrial scale human storage facilities.
Go live in one of you want to, share that one sad looking tree in your one sad looking park where you’re not allowed to walk on the grass with ten thousands of other people.
Don’t forget your antidepressants and your sleeping pills.
