That works until all* games come with root level anti cheat. It was the same with micro transactions which people still defend despite being utter shit.

• Realistically this will never be 100% but it will be enough of the mass market AAA games like CoD etc to mean that if you functionally want to play a game made in the last X number of years you will need to accept this or stop playing games altogether.

They may never even know about it.

Proton is not actually sandboxed the way an actual container is.

A) if the program running in proton was given root access in some way, say by tricking people into entering their root password for a claimed update, it would have complete normal control of your entire system just like normal.

B)apps running in proton still have access to the regular file system.

Wine isn't an emulator or a vm.
