Yes, you can. But a lot of Windows users dont even know what powershell is.
And personally i think you shouldnt have to jump through hoops for what i consider basic functionality. They also make it near impossible to install Windows 11 new without having to resort to all kind of tricks to create a local account. Its a shitshow.
Thats because a lot of users dont really want to use Windows, or the computer in general. They use it, because they have to.
For the same reason, i would never know what to do when my car breaks down. Sure i can look under the hood and do this and that. But its not my area of expertise, and its not something im interested in.
I'm a sysadmin, i know almost everything about powershell and then some. That doesnt mean my users do though. For them, a computer is a magical black box thats supposed to "just work" by clicking here and there. Just like a car is to me :)
Sure you can. You can also spend time disabling intrusive telemetry, you can also spend time reverting half the UI changes (not the other half though), you can also spend time removing integrated services you don't use but are still running, you can (regularly) change back some settings that gets reverted every once in a while, you can also block some IP to prevent intrusive ads, you can toggle off part of the "user experience" that bloat the lockscreen…
Or you could, I don't know, not have to do any of that and still have a working system that's not trying to bend you over.
