I agree with you wrt the battery, but I would prefer to put an aftermarket case on a more fragile phone than to buy a rugged phone that supposedly doesn't need a case.
Both are going to be badly scratched up if dropped on or dragged across a rough surface. A cheap aftermarket case, though, is much easier to replace than the backside of a phone. In other words, a replaceable case has many of the same benefits as a replaceable battery.
