I know, right? You can just get something else he’s interested in. Like OP, maybe the kid likes antiquities, you could get him some from Benito Mussolini’s 12000 piece collection in the Colonial Museum. Or maybe he likes art, you could buy him one of Hitler’s paintings.
Then explain perma-ban
Joke aside though - ban is a toggle. You can toggle something on or off, but it usually implies something temporary. You can then manually unban someone at a later date, or have the unban be automated in some cases.
“I turned the lights on” - there is no expectation that you never turn them off again
“It is snowing outside” - at some point it will stop snowing
“I’m banned from my local book club for repeatedly asking if they made a movie for that one” - this too shall pass. Maybe in 4 years when I go back they’ll forgive me and let me back in, and by that time I’ll have watched Moby Dick - manual toggle of the ban back to ‘off’ is expected here.
“I was banned from Day9’s stream for backseating” - here the ban would have an automatic limit, maybe something like a million seconds.
