Note that I said average person. They will never touch a command line, so apt-get is out, and the Ubuntu Software Center is buggy as hell. Compare that to macOS: Drag app in .dmg to 'Applications' folder: installed. Drag app from 'Applications' folder to trash: uninstalled. Need to remove all settings? remove the apps' concerning folder in ~/Library/Application Support and plist in ~/Library/Preferences. Yeah, I'd say that's pretty simple. And although the Mac App store has its flaws (draconian sandboxing) it also works like a charm.
