If you can't wire a house after 2 weeks of education, they were going to burn your house down anyway (especially if you are using AFCI). It's like one simple and highly redundant 300 page book of information at worst.
I will never understand why electricians are always held to this kind of standard and reverence. Framing my house took 10x the amount of study and learning than it did wiring it, and that included me doing a mains underground power extension and all of the mains meter and breaker.
I have to assume a huge amount of it is national and local regulations, which seem to change every freakin year. I read relevant sections a decade ago re: outlets with no ground(has to be on gfci breaker) and wiring a bathroom(has to be on separate circuit). Now you're apparently not allowed to put outlets on the side of or back of kitchen islands? Just random things like this.
I couldn't imagine having to keep up with all of it. I'd guess many don't...
