I share your general concern here, but this is not how email-based service logins work. Excluding account creation and password resets, third-party services don't require you to access your email every time you log into them. For the most part, the login process simply treats the address as an identifier.

The actual consequence of the scenario you describe would be logging in to each service and changing the email address associated with it. But the idea that you'd be locked out, especially from your money, is just not realistic.

My bank uses 2FA in which they send a pin to my email on login (I know it's not the most secure thing, but it is what is being used). Though if I lost access to my email, I can go to my bank branch with identification to get it changed in 2-3 business days - during which time I won't have access to a number of online banking services.

Steam also has the same system.

Did you ever came across the wonderful "sign in with Google" functionality?

That's a good point. Though it is an importantly different point: it's trivial to avoid this feature, to the point that I've never once used it.

(Though I gather that there have started to be exceptions, as with dating apps. If this becomes more widespread, I'd agree with your concern)
