SteamOS is a much more streamlined console-like experience for gaming. Even things as simple as system updates is far less annoying on Linux/SteamOS than it is on Windows. This is especially important in, for example, a set-top box media PC you might want to have for your TV and you don't run every day. And, over time, as SteamOS in its various forms becomes more and more popular, game publishers will be motivated to support it. Many already are, from Steam Deck alone. And, in a few years, it's possible that a "casual PC gamer" will actually prefer the far more plug-and-play SteamOS experience versus the Windows one (which, I, for one, highly dislike, but I understand that's a preferences thing).
