I could also be hit by a car, get cancer, have cosmic rays wipe my hard drive, etc. Getting permanently locked out of my email is an event so unlikely it’s not worth thinking about.
Both of which I pay for.
Turns out losing both my laptop and my phone simultaneously was enough to lock me out of both forever - LP wanted me to click a link sent to my email to login from a new device, and said email account (GSuite) required a password stored in LastPass.
I largely gave up after 3 months of trying, and created new accounts for everything.
Years of work lost largely due to being stonewalled by Google support at every step.
My current best hope for recovery is that the recent lastpass breach data goes public and I can crack my own vault using the passphrase I know for it.
Maybe double check the "try another way" login options and maybe one of them will help you get back in.
Good luck!
