Building homes on federal land in the middle of no where will not do anything for people. We just need to allow people to build housing where there is a demand for labor.
Some things I think would be solved include:
- the housing crisis
- mobility => it would be easier for people to move to other parts of the country because they would be less tied to their homes - labor mismatches
- climate change => less reliance on cars
- funding infrastructure => more dense infrastructure means you don't have as much infrastructure to repair and you have more people paying for it
- city government budgets => high density areas are more tax efficient
- home insurance => the homes on the outskirts of cities are most likely to burn down; if housing is cheap the cost to insure it will be cheaper as well
IMO, if housing is 30-60% of peoples budgets and transportation is another 10-20%, if you can bring those costs down you can de-stress a lot of people. That might make politics less intense too.
* "Most problems" is not strictly accurate. But "more problems than you might think are directly related to housing" doesn't really roll off the tongue.
