fair enough, but that's a different argument. and when it comes to a mortgage your alternative option is renting, and the worst case scenario that you can't pay rent or your mortgage is the same.
it's not like a car where you have the option to do without, you can't do without a place to live. i am pro renting, but unlike a car loan i don't see a mortgage less financially responsible because you can almost always just repay the mortgage by selling the house, in other words unlike any other loan mortgage is unlikely to put you into a debt that you can't repay because the house is your collateral. (unless the housing market crashes maybe)
