People that can't afford things tend to pay little tax, if any. They are net receivers. And how are people that bought something with their own money subsidized?
Indeed, actually owning land rather than leasing perhaps should not be a right of private entities at all.
But a place to live is obviously a requirement of existence, and therefore must be a right.
As for 'own money' etc, it isn't god-given out of thin air, but results from our current system of organizing work and distributing rewards. Some would say that system is unfair, even rigged.
Owning land is not a birth right.
