The Shrill One makes what should be the obvious point that home ownership isn't for everyone. I previously pointed out that Miserable Failure had failed to increase home ownership, something which was long a centerpiece of his domestic economic accomplishments, but I don't really consider it to be a failure that matters.
I don't object to all policies tilted towards home owners. There are some good reasons to have policies in place which make it possible for people to, if they want to, buy homes. But some people are mobile, some people don't want to deal with the additional responsibilities, etc.
