I don't have numbers, but I would be fairly confident in a guess that many, many more houses burn down because of a combination of open flames and carelessness, than do because of low-level DIY electrical work.

Using matches to light a stove or fireplace is so common that we've as a society decided to not place restrictions on that activity because the cost outweighs the benefit.
However, doing electrical work on your house is not quite as common and the result of your work will stay with the house and possibly affect future owners. Added to that the work is generally hidden or not obvious and future owners may not know about your substandard work.
Yeah it's a totally arbitrary line, but either we license nothing or we just pick somewhere to draw it.
My original comment was because in the UK most of this stuff isn't licensed* - even installing a gas stove doesn't need a license, which I'd argue is a lot easier to screw up than a light switch.
There are 'regulations' on how things should be done, but these are merely guidelines in most cases - you won't have any issues with the authorities when trying to sell your house or with insurers if it's not up to scratch. It would be interesting to see how accidents caused by this compare in the UK and US.
On the other hand two things we do strictly regulate are 'listed' buildings and the removal of trees in your garden.
*I think the same is true for most of Europe.
