> Let's build some more of that so we won't need to drive anywhere

Have you been to the projects? There's housing, and nothing else. People still have to sit 2 hours on a bus to get groceries because it's still a food desert. Businesses won't show up because there's no money, because there's no job training programs and no public transit to where the jobs are, etc. Eliminating segregation and raising people out of poverty is complex, and I don't think eliminating environmental review would move the needle.
