clearly there's something I don't understand (or is the law just really this stupid?) - but what would this even look like for linux? every user account requires an associated age?

but users don't have a 1:1 mapping to the people that log into them. linux users that aren't used by any particular person, but by a particular _service_ are common. so are linux users that could be logged into by any number of people, and which have no specific single owner.
