Would it be possible for Apple to just encrypt this data or, not keep this data? Then there would be nothing to give law enforcement or government. (Forgive my ignorance, I have no idea how all this works.)
The developer of the app sends the push notification through Apple’s service. Developers have always been able to encrypt it, at which point it can be decrypted only by their app, but not all developers do this. There’s also still limited metadata about the fact that a notification was sent, even if the contents are encrypted.
Would it not make more sense to remove metadata and not even collect it? Maybe have an encrypted protocol for push notifications all developers use regardless of the app?
Your phone has to be informed somehow, from the internet, that it has data to present as a notification. The fact that you got a notification at 3:32 and then again at 3:35 is trackable data, pretty much no matter what anyone does with it, encrypted or not. Doubly so if someone has MITM attacked your data stream. They may not know what the notification contains or even what app it was sent to, but the act of transmitting and then receiving this data packet over cell network or internet is a trackable event. And I don’t really know what Apple could even do about that beyond attempting to build Internet 2 solely for the purposes of keeping the cops out of it, which is unlikely at best.
Why not chuck the data when it’s no longer being used, though?
They do. Apple is sending literally trillions of push notifications per year and certainly doesn’t want to save them longer than necessary (a useless expense), but the government can also ask that information for a targeted user be retained, going forward from the request, even though it would normally be purged.
It’s possible that they could encrypt and anonymize this data with yet another set of tokenization, but that would be quite an effort on their part. As for not keeping the data, the metadata, itself, it’s necessary in order to coordinate the sending and delivery of push notifications between apps, services, and your devices. It needs to exist.

Because protecting user privacy is not a priority.
