A terrible waste of what? Should I invite more people to live in my 1954 house? Should I have kids (you want to talk about environmental stress, just have some kids!) to make it impossible to have a home office so I'll have to get a job where I have to drive to work (actually, these days I typically fly to work, oops)? Should the sellers have picked a larger family to sell it to?
Where do these arbitrary rules come from?
