As I pointed out, it is not a manual and painful process You can do it with GUI apps, even though it is not Linux style package management. Such apps will be far more comfortable for many Windows users than PowerShell and CLI.
Chocolatey has a GUI as well. But you are right, most windows users don't understand the pain or are so dull to it because that is what they have always seen.
Now imagine running one script to keep all of your software up to date. So every morning when you start using your machine you have the latest software automatically. That's really setting up a file that runs some commands and maybe task scheduler.
You can say there is no pain, but how long does it take for you to ensure that maybe 10 apps are up to date? 50? 200? What if you never needed to do that again freeing you up to worry about more important things? Just because you may not feel the pain does not mean it is not there.
