Why doesn't Big Can make their cans nestle the tops and bottoms to fit together?

I don't especially like the cans with pull tabs. I always use a side-cut can opener on them so I don't slice up my hand when I try to scoop out the residue.

I don't and do.

The only cans with pull tabs that I've come across don't cooperate with my side-cutting opener. The lid is recessed more than most cans and the cutter just barely gets the top of the rim. This results in the lid almost always not being completely cut, difficult to open, and impossible to 'close'. So the pull tab wins. But it's only one item so I live with it.
