> None of that is realistic anymore

It's not realistic when you have unrestricted immigration, as the US states have between each other.

Or you could have PTSD or just vanilla noise-sensitivity and just living in a quiet neighborhood could be extremely important to you. You might have made very significant personal sacrifices to afford to move to a suburb for exactly this reason. Should you just be forced to go live in the woods as a hermit, cast out by society?

Well, unfortunately, yes. I don't want to sound heartless, but sometimes the needs of the many do outweigh the needs of the few. This isn't "tyranny of the majority" here.

It's incredibly selfish to use PTSD or noise-sensitivity as a justification for contributing to a situation where tens (hundreds?) of thousands of people have 3-hour commutes when they could otherwise live closer to work.

If the city up zones your suburb can empty out making things better for you. It is only those who like their level of busy not far from downtown that will get pushed out.

>making things better for you

Ah, surely there is nothing open interpretation there.

You can sound proof a home. It's very common in NYC. Not everyone can live where they want. That's life.
