No, the actual way forward for large scale preservation requires donning a pirate's hat. The people really doing legitimate preservation work are largely doing it outside of the purview of the copyright holders (and often in direct opposition to the rightsholders' desires). This has always been the case and will continue to be the case as long as copyright remains in force in the current form.
Preserving the games themselves, including server components or emulators, is key to this. As it stands, it already requires there be someone with the personal interest in a specific game, and the technical ability to crack it. Without that, such a game won't be preserved no matter what. Requiring publishers to make such things available at some point can only help. It removes or mitigates that later requirement.
Digital games can be pirated. DRM that runs on the client can be fooled or bypassed with enough effort. Storage is becoming cheaper as time goes by. Time is generally not critical for any of these.
Unlike all of these things, reliance on servers has no real solution and is a guaranteed ticking timebomb. Many games released today (manly "live service" games) have no offline mode and simply cannot fully function offline even if they're reverse-engineered and modified to do so, because a significant part of the game logic code and data is simply not present on the client. Often the only real hope is attempting to reverse-engineer the server logic and capture relevant data via packet sniffing so custom server software can be developed that emulates the behavior of the official servers accurately enough to allow the game to be played, but games nowadays are becoming so complex and game logic is becoming so intertwined with the servers that this is simply not a feasible task unless you have direct access to the server data somehow.
Unfortunately, this is a problem that has largely not manifested yet, so most people don't yet realize it's a problem. Live service games only started becoming the norm in the last decade, and the vast majority of the popular ones are still in operation. In a decade or two, most live service games people love today will no longer be playable due to the servers being shut down, and developers have no financial incentive to allow them to be playable after that. Will a solution be found before then? Probably not. I'm not looking forward to it.
