This causes far more harm than good - even this article admits SMS 2FA is better than nothing. For several 99.99999% of use cases, it is fine, SIM swapping is an extremely targeted attack. If you are the type of person that can be targeted by an attack like that, don't use SMS for anything important. Simple.
This would still be a targeted attack if exploited, and arguably much more difficult than sim swapping. And yes, I did RTFA, and my point still stands.
