I have neither a Google nor an Apple account.

Well, to be fair, I do create an ephemeral Apple ID every time I get a new phone… But I immediately log out of iCloud after downloading the two or three apps that I use. I have no idea what my Apple ID or password is… I would have to go look them up.

Further, if I lost said Apple ID, I would lose nothing of value.

I believe, as you say, I exist meaningfully in society.
