Not having the skills isn't the thing that should stop someone in either scenario, it's not wanting the skills. Arch is great for a beginner that wants to know how to set up their own bootloader and similar things, you can use Ubuntu for years without gaining that knowledge. Or how much C editing and compiling does the average Unix user happen to run into?

There's very little natural progression in computer use, people do things the way they know how until they decide to learn more. Think of how many time's you've seen some family member slowly select file-save without ever figuring out ctrl-s.
