I spent years looking for the "ideal" spot, and an absolutely ridiculous amount of money to obtain it, and 6 months later zoning rules changed and screwed everything up. I've just learnt to live with earplugs, but not everyone can.
More importantly, to house everyone efficiently, we need high density areas. If we must put a lot of people so close to each other, AND we agree that sleep is critical to one's health, we should treat it the same way as we deal with drinking water rules, fire safety, health code, etc. The laws should reflect and be enforced to match how important it is.
Step 1: While the existing laws and ordinance suck, they're better than nothing. Let just starts by enforcing them. No one's fundamental rights are harmed if you get in trouble for driving an 18 wheeler backward in a residential zone at 4 in the morning.
