This is probably useful for most non tech people, who might forget their passwords / lose keys, and don’t want to lose all access and all data.

If you’re tech savvy, you should probably enable ADP, I did it few months ago. When enabling it there’s multiple warnings about how you’ll end up completely locked out if you lose all your devices / lose recovery keys / lose all hardware authenticators. Iirc I was also forced to register at least 2 yubikeys.

I have ADP on and I have no yubikeys. I also can't imagine Apple requiring you to have them.
