Where does this attitude come from? It's like saying "Well, I could hire someone with a power-tool to fix up my house, but I don't know how those fancy machines work. I know! I'll hire that old carpenter down the street and watch him work over his shoulder!"
It comes from the fact that the power tool user won't just fix your house, she'll also yell at you about how the design is bad and you need to be doing these other six things to fix it. The carpenter will just shut up and do his job.
So if you're someone who wants to plan your own house (and especially if you're someone who feels like you need "authority" to do it) you have a built-in incentive to ban power tools from the workplace.
