Then just keep doing things the same way, but add a disclaimer that says you are only selling a license to play the game, and it's not guaranteed to work after a certain date.
Then like what happened with the cookie banners, everybody is going to put the minimum date, and the only winners will be the lawyers selling consulting in EU regulation compliance with the publishers.
You are begging the question, the question being whether consumers care. You believe they don't (e.g. that the expires-on date won't affect sales) and the creators of this petition believe people will care and will prefer games that do not have that expiry date.
So no, it's not inevitable that every game will just sprout an expiry date. It's possible but only if you're right that consumers don't care about owning versus renting games.
