Fraud becomes harder because unauthorized impersonation of someone else's number becomes illegal and is (hopefully) technically prevented.

Because of this, you can just blacklist spammers again, and burner numbers for them become harder to come by.

This is the correct answer. Forcing all numbers to be authenticated doesn’t stop scammers from calling you, it just makes it easier for you to make an effective blacklist. (A blacklist around which Apple and Google, etc would be wise to make a good UX.)
