> If I don't know a feature exists, clicking around through dozens of menus isn't going to get me anywhere.

I find that clicking around through menus often teaches me about great features I didn't even know I wanted.

Regardless of the cause, in practice, I find that it's much easier to get basic functionality out of a new-to-me GUI app than a CLI app. That may not be a fundamental properly of CLI, but it certainly is how all significant CLIs are written.
