You're right, what I actually should have asked is "How do you guarantee I never lose access" If I lose the key to my house, I can change the lock, it's my property. If I lose the key to my Post Office box, the Post Office will charge me money to set up a new key. I have RIGHTS to my physical property and physical business relationships. What happens when I lose my Fastmail key? Currently the status quo is "get fucked". Which is utterly insane to me. My options in that reality are to either, set up 2fa and ensure that I lose my digital life at some point, or not have 2fa and get my shit taken instead. Google doesn't do much in that regard, other than making me confident that they won't let anyone else pollute my ad profile, but I was an actual child when I set that up, and it doesn't cost $5 a month.
