You still have Box64 and Box86 to run most if not over 90% of 64-bit and 32-bit applications on an ARM CPU. I don't think you understand the versatility of the Linux platform.
The point I was trying to make is running things through Wine or Proton is not a one shoe fit all scenario. Also it's annoying when people say "Just run it through Proton or Wine" because running any game through a compatibility layer always takes a hit it performance. Also you can run into functionality issues with some games. This is why people ask for Linux ports because it fixes most of these issues and also gives you more freedom and options when playing a game.
Alright. The only thing I'd say about this is what most people have said already. Maintaining multiple ports bears real, non-trivial cost, varied by the libraries used, and it'll be a long time before the Linux marketshare is large enough justify the investment to most dev teams (in spite of being disproportionately vocal). Imperfect as they are, P&W are needed to bump those numbers.
It seems like asking for Linux ports is kinda your thing, so I'll leave you to it.
