There's a community near me that has enormous housing shortages and yet they maintain a 1 acre minimum lot per single family house only to "preserve character". Does that sound like a safety issue to you?

It could or it couldn't. It depends on how many people currently live there and how many people are _trying_ to live there, and how much is available for sale at any given time (e.g. real estate liquidity).
I'm partly joking, partly serious. The current state of affairs is roughly by design. At some point USA is going to be forced to have this conversation: how much socialism are we going to have? Are you going to deal with angry "homeless" or is universal housing availability so fundamentally good for society as a whole, that the government is going to enforce it some way, even if it comes at the expense of already housed?
Also people aren't homeless because there are no "homes", it usually runs much deeper than that
