The argument put forward previously was 'people were starting families without X, therefore people not having X isn't a problem', where X was a house.

I was trying to demonstrate that no matter what you substitute for X, even something extreme like basic human rights, people were still starting families, therefore either we should not be concerned about anything, or the argument is flawed.

Also many people were rendered homeless or pushed into poverty by the current housing crisis, and I am sure those folks find the argument proposed above offensive and inflammatory.
