There may be scattered small neighborhoods in very large cities where this is possible, but it's largely illegal to build this way in most of the US

Why would you want to have to drive everywhere?

It's quiet, I get a larger piece of land with a yard that I can enjoy, I can have a porch, there are no homeless people accosting me when I sit on my porch, when I go to the grocery store it is clean and doesn't have a homeless encampment outside the front door, and nobody shoplifts from it so nothing is locked up, etc etc. I used to live in Seattle, these are not invented problems.

50% of your problems are homeless people. Seattle should get homes for those people and that would make it 50% nicer for you.

Yes, Seattle would certainly be much nicer without the homeless people, no argument there. But even if we assume that would reduce the crime rate, I still would prefer my large SFH with a garden and allowing my kids to safely run around the neighborhood unsupervised.

This is not mentioning the gorillion dollars Seattle already spends on homeless help to no avail; asylums are probably the only real solution to that.
