> you are setting yourself up for losing your account forever if you ever forget to transfer all your 2FA numbers, or if the phone company decides they want to cancel your contract, or potentially if you lose your SIM card, or even if whatever SMS gateway doesn't like your number for whatever reason

Its the same with your address, what if your landlord randomly decides to kick you or your house burns down? Where I live my mobile number is very secure and will not change until I fuck up very hard. And in this case I have multiple other backups (printed codes, rescue number).

Not the same at all, you can just go to the post office and file a forwarding address and all is well.

Phone numbers are very ephemeral. I have many phone numbers associted with many older accounts, like one from an office phone from a company that doesn't even exist anymore. Learning from those lessons, I go out of my way to never associate a phone number with anything anymore, it's just asking for future pain.

Then I can go to the post office and talk to a human who will happily confirm who I am (maybe they even know me personally) and can forward my mail anywhere I want.
