We are our government. You, I and everyone else. Are you willing to support putting in place legislation, regulations and policies and also be willing to pay for them to provide sufficient and affordable housing?
My guess would be NO you would NOT and thus you and others like you are to blame for the lack thereof.
To reply to the second sentence of your above quoted post, I would like to buy up properties that surround your residence and short term rent them to a revolving cast of characters, be they loud and obnoxious morons, just released convicts, asymptomatic covid carriers etc and you would have no recourse to stop me. After all according to you I "should be able to rent to whomever I want."
