I agree this not for the untrained.

We all do many thing everyday that are potentially lethal to us and others.

Locking out the main before connecting the generator is a very simple proceedure compared to driving a car or shooting a gun at the range.

A transfer switch takes it to idiot proof, similar to only being able to fire the gun when it is actually pointed at the target.

I am NOT advocating the backfeeding of utility lines. I am merely trying to better understand the mechanisms of danger and assign some relevance to them.

Closing your eyes and firing a gun is dangerous. But if you are alone in the woods the danger is different than on a crowded sidewalk downtown.

The generator danger occurs when ALL of the following occur at the same time:
1. Power line breaks between single house and grid.
2. Generator operator fails to isolate main.
3. Lineman does not measure line.
4. Lineman fails to install ground.
5. Lineman touches line on transformer side of break knowing that he is violating his work rules regarding #3 & #4.

#2 is prevented by a properly installed transfer switch.

If the Electrician is incompetent to lockout the main, is he competent to install the transfer switch?

A tranfer switch is the best solution.
What level of operator competency makes other solutions viable?
