Why commit to small differences in an entire inventory/supply chain problem for a very complex and expensive device instead of a thin wrapper?

Phones are thin! The case makes them reasonably sized. Treat a naked phone the same as you would a naked human: unsuitable and unprepared to go outside.

But if phones were built more durable would they be smaller than the thick case or could they make use of the extra space that a case requires by having larger batteries, etc.

This. I don't want to use 3mm of leather to stop my phone wobbling on its stupid camera-lens tumor. I'd much rather use 3mm of more battery.

I never get a phone case. I’ve dropped my iPhone XS I don’t know how many times. Not a single scratch or crack on it. Pro tip: needing a case is a marketing gimmick “it’s made of glass!”
