There's a difference between sneaking through App Store review and not enforcing anything at all. People still shoplift even though theft is a crime, that's not an argument against having laws.
No. Apple provides a door (advertising ID) but there's also a window (fingerprinting). Right now both things exist. Apps already have the ability to fingerprint users with data they collect and that's not sneaky.
That's a strange argument though. Apple forks over an advertising ID so that any app can fingerprint you with a single system call yet you complain that more apps might in the future fingerprint you themselves.
Without app review there would be no practical way for end users to avoid fingerprinting.

Only if you don't consider consent. A user opting-in and enabling the advertising ID is very different from a bunch of apps using third-party SDKs to fingerprint their device without asking.
