As much as I avoiding any Microsoft technology at any cost. I do have a gaming rig at home, and yes I have Windows on it. I only use it to launch Steam and GOG, nothing else except the casual web browsing. I have been driving Arch btw and was fine, but these days you CAN install Windows 11 locally without Microsoft account. So I took it a shot for better game compatability.

This is not Linux/Window flame. I am trying to say, local account is possible and is working.

It's certainly possible, but it certainly ain't a happy path. If you have to do shift+F10, strategically disconnect your ethernet cable, or remember to tick a box when making your bootable USB to be able to make local account, something has gone terribly, horribly wrong.

Afaik local accounts have become harder and harder to create, intentionally, to the point where it's impossible for most people. It most definitely is not something that can be relied on to exist in the future.
