Cause I don't know where my 4 jackstands are and would just feel better about myself knowing the car was on the ground for a week-or two. And I don't want the frame to flex/crack the windshield(i've seen it happen before and I have a chip in my windshield that could crack if I do this) because I don't think my garage floor is exactly flat flat...
Worst case scenario, I'd put it up on jackstands.
