Political Memes

You clearly just don't like the policy, but all of your points have responses.

1. tax more. Literally everyone on the left agrees with that
2. More money in the economy is more opportunity to tax. People that need this benefit will be most likely to actually spend their money on good and services. These programs will also give homes and stability to people so that they can get out of cycles that impede their upward mobility and cause them to continue to depend on benefits.
3. it is not irrelevant because this would not be a check for billions being written overnight. There would be a roll out to ensure stability and work out issues with the market
4. never said no penalties for defaulting and plenty of people with bad credit need housing and are being provided with it by the government anyways. Might as well not give that money to 3rd party landlords that drive up rents. Also, this is nothing like PPP, other than that the government is involved.
5. the government would operate like any bank would. It would not allow a 500k loan for a house not worth 500k. You're not guaranteed a number. That should have been clear based on my above comment that mentioned potentially upgrading to a different house when your income increases. Houses aren't just more expensive because fha loans exist. And again, all of this would be in a market where investment properties aren't really a thing.

If you don't think the government should be involved in housing, you can just say that.
