IMO more high density housing is a good idea in city centers where you can walk to run errands, shop, eat out etc. Many young people who don’t make much money would enjoy having a cheaper shoebox to live in, where they don’t have to worry about driving drunk to get home. As their income improves and they build a family, they can opt to move a few miles out to the suburbs where you can have more space. Many East coast and European cities have that exact design, and are well served by both road and rail service.
That said, even with more high density housing, cars and distance between work and home will likely always be an issue for the vast majority of people.
