Which begs the question why bother with Linux then.
As for privacy and control discussion, when most GNU/Linux users happen to mostly consume Electron and Web Apps, install applications via curl | sudo sh, there is hardly anything to discuss, other than cargo cult of a false sense of privacy and control.
Pity that all that security goes away the second an Electron app or Chrome is made use of.
You're making silly arguments based on your own strawmen.
But really, reality is that Linux support for games is still caught in the cycle of too few customers to bother -> customers want better Linux support before moving over -> too few customers to bother...
So I can now have all the (my) benefits of Linux and enjoy gaming that otherwise I wouldn't.
Also, you used "begs the question" incorrectly. You mean "raises the question".
Also, because Windows is a steaming pile of donkey turd that shoves ads in your OS, reboots when you're trying to get work done, resets privacy and power management settings after many of its coerced updates, and has a spazzy and inconsistent UI that offers limited customization. Also closed source.
It most certainly works out of the box for most general tasks.
Of course there are still limitations like a lack of some software (Photoshop...) and peripherals support, but these are becoming far more uncommon. I even find with Steam's proton implementation I can install and run most Windows games without a second thought.
