FTR Mersey, I hope my response didn't come across harshly....

I simply meant that there are solutions to the obvious problems... and I think the problems with 'what we're doing' require risking some of the concerns you have. We've done it this way for decades now and things are worse, not better for most people subject to them. We need to find a way to fix your concerns. I don't pretend to have worked out all of the kinks.... I just think that 'having to find a way to address public transportation' in the age of internet and delivery and work from home etc is far less of a concern to me than people who quite literally have zero upward mobility because we have denied them access to what is perhaps the single largest source of wealth creation in the history of the world.... even if we DID have good intentions.
