I don't think live services need to be banned.
CSGO, Fortnite, Hunt Showdown, Apex Legends, etc are all long running multiplayer games that just don't work outside of some version of the live service model. Only the top of the top games have the numbers to keep people buying a new version of basically the same game over and over again without fragmenting their player base to the point where the series dies.
Live service games (when done right) effectively let those that have more money pay for stuff they want and people that don't want to pay more than an initial entry fee (if anything at all) don't have to pay.
I think the better thing to legislate is that if you have a live service game (like Hunt Showdown) if you shut it down, you must make it possible for third parties to continue to offer service. i.e. you must at least provide a server browser, private server executables, and disable any anti tampering software that prevents the game from being modified.
That would be pro-consumer in that it would keep the game (in some form) working for many many more years. For game developers that do run successful, profitable, live service games that people like, they can keep doing what they're doing for years to come. For game developers that keep pumping out live service as a way to milk extra money from players that already bought a full priced game ... they might think twice.
