There are going to be tradeoffs one way or another. You can build a bunch of high rises and fill them with people, and private transportation will become impossible. The experience of going to the beach or some hiking spot on the weekend will be degraded. Everyone will be living in a godawful megacity instead of the nice neighborhood they'd rather live in. There's a reason people push back against growth with respect to housing. The real problem is overpopulation. If you eliminate one negative feedback loop for population growth, you will ultimately run into another one, and all the different kinds of waste we produce (CO2, garbage, light and noise pollution) will only pile up while finite resources in the region (breathing room, nature, water, room on the road and on hiking trails) will be divvied up into smaller portions
