Speaking as someone who has built local-only apps (partially because I don’t want the hassle of maintaining a server):
There are plenty of useful apps that run locally on a phone. You can even run a whole LLM on your phone.
The shiniest and most popular apps are cloud terminals but the iPhone is actually a pretty darn powerful device.

They are powerful from a computational perspective, but the point was that it's a hassle to run a custom binary on them as compared to regular computers. You get a powerful device that is not flexible in this specific sense, so much of that power is not utilized
Plenty of useful apps != general purpose computing capabilities.
You are not allowed to run computations that have not been approved by Apple if you are using an iPhone. Yes, the hardware is powerful, but it is cryptographically locked down. It is physically local, but the control of the hardware is entirely non-local and 100% owned by Apple.
You can run arbitrary computations on iOS devices if they're written in JavaScript, WebAssembly, or Swift (via Playgrounds). All of these are Turing complete, and all three compile into machine code. What you don't have without an Apple developer account is direct machine code access.
Also note that apps like Pythonista allow you to write programs that call arbitrary Objective-C APIs without permission from Apple. This means that you have a Turing-complete language running unsigned code that can do anything a signed app can do. Your programs do, however, execute slowly.
unless you're using an API that requires an entitlement, you can still get an apple developer account and sign whatever code you want and run it on your devices.
So if they don't give you an apple dev account, or close yours, you can't.
Case in point.
