I think that's a poor analogy.

Most residential wiring really is as simple as it appears at first glance.

The problem is that there are a few cases where it isn't, and the issue is being able to know when that's true. This is where the skills and experience come into play.

In case I need to cite some authority, I've been wiring my own homes (with permits) for > 25 years, and was licensed by New Mexico to install my own 6.7kW solar array a couple of years ago. I'm not an electrician, however.
