Depending on how the law is implemented, I can think of a number of ways that studios would try to get around it:

- If the law says it only applies to games which are purchased for an up-front cost, then make the game free-to-play but with microtransactions

- Include a single-player campaign, which will remain playable even when the multiplayer or game-as-a-service part of the game goes offline

- Just don't allow EU players to buy or play the game

If this were to become law, I expect that it would result in many more games with offline solo play, rather than resulting in more games where the tools to host your own server are provided. That's still probably a victory for players, though.

If that happens it would be suboptimal but still it would be better than what is happening right now. If that happens the game is still going to die at some point but at least company will be upfront about the fact that gamers don’t own but rent/lease their games, and gamers will know when they stop being playing a game (when they stop paying for it, that is).

What happens now is publishers sell games like products - for a single time fee and they don’t let you know when you will stop being able to play the game up front. Then some day they shut down the server and nobody ever can play the game again. Imagine Amazon deleting books you bought from your kindle account. That’s what’s happening now.
