Paid games should remain playable after official servers shut down

I paid €60 for a racing game in 2019. Single player career, the whole thing. In March the publisher turned off the servers and now the disc boots to a login screen that can't log in. Not "the multiplayer is gone". The game is gone. I test software for a living and I know exactly how much work it takes to ship an offline patch, because I've filed the ticket: about a week for one engineer. They chose not to. If you sell me a thing, the thing should keep working when you lose interest in it. That's not a radical position. It's the position for every other product on earth.
