If you think the US should be doing more the shelter people without adequate shelter it should do so directly. Creating market distortions that purposely reduces the value of property and discourages production of the good is not the way to go. That would be like banning expensive restaurants because they're running up rent on inexpensive restaurants and soup kitchens. After all, desert is way lower on the hierarchy of needs than basic sustenance and food is not a need that the US is adequately meeting even for its middle class
What kind of actions are you considering that do not affect the market? Government housing affects the market by creating artificial supply. Regulations affect the market. just about anything that the government does will affect the market.
If you believe that housing is a basic right and everyone should be housed, then relying on supply and demand is not going to work. There's nothing inherent about a market that would house everyone, if anything, a market would reach an equilibrium where supply meets demand at some point where some people are not able to afford the supply and suppliers do not have an incentive/are unable to meet the price point of the remaining demand.

Zoning laws already create market distortions. A zoning law that prevents building denser residential property is no more or less distortionary than a policy that prohibits short-term rentals.
Also, reducing the future expected value of property does not discourage builders; they only care about the sale price today (or, today + build time).

Restaurants are also far higher on the hierarchy of needs than shelter.
We do distort the market in favor of soup kitchens -- they have substantial tax benefits and in many places they can operate out of differently zoned property.
