I disagree, it is the baffling romantization of plumbers and tradesmen as some kind of a social panacea that is the problem. Here you have already predefined for yourself what plumbers are and how they should function, and so you employ this biased construction of plumbers for your post, where it is nothing but fantasy.

Don't be too hard on yourself though, you are only subject to the current shibboleths of pining for these fantastical tradesmen (possibly a result of some kind of desire for a safe simplicity), and so you only regurgitate these popular sentiments (that feel so good!) without being able to consciously check your delusions.
