Why staple NM?

I understand it is code, no disputing. I'm wondering the why behind it being code.

Here's my questioning. If it is loose behind a wall and someone nails or screws into the wall, the nail/screw will touch the cable, but the cable will move and won't be drilled nailed into. If we staple to a stud, then not only is it fixed with no give, it is also attached to a target for mounting.

My next part is repair/re-wiring later. If the wire is loose, you can use the existing cable to pull a new cable. If it is stapled, you have to remove part of the wall to get the old cable out of the way.

Just a curiosity.

As for repairing, we prefer to wire to minimize repairs rather than to accommodate them.

Cables and wires very rarely go bad outside of outlet and junction boxes.
