The problem with saying this is that while it makes sense if you connect the dots, the path of those dots isn't direct so it's non-obvious to some. A government spending that money can't just build housing and have it solve the problem through market forces because the government won't be participating in the market that way. What a government has to do is incentivize the market, and through incentivizing the market (even if that's taking out many disincentives that have been put in place) cause market participants to build more housing. So, while saying "just build more housing" isn't wrong, it's not a useful way to communicate the concept of do whatever it takes to encourage more housing to people that aren't already on board with the idea.
