Thank you, I value my tender bits!
Basically, your comments are anecdotal. That doesn't make them invalid but it does limit their practical application. You also misinterpreted a few of the statements. You may be able and willing to rewire your own (or someone else's) home, office, or building, but that doesn't make it practical for the average person. Those frail mortals would need to hire someone to do the work.
As well, you appear to have missed the fact that the 90-ft extension cord was just an example of a condition, not a final solution.
You appear to have a good basic grasp of things but if you spend less time ridiculing and more time analyzing you'd probably serve yourself and others a lot better.
