even then you don’t need this recurring manual registration mess.

There is no recurring manual registration. You only need to register once in your lifetime.

If you move, you have to update your ID within 60 days, and every time you update your ID, they update your voter registration automatically. (unless you decline).

That has been federal law since 1993, and is pretty much equivalent to European standards.

You really have to go out of your way to not be registered to vote.
