Just want to say the push back you're getting on this topic is one I've experienced everywhere - the actual work of the trades is basically treated as an unknowable black magic which only it's arcane practitioners can do.

Which I think is partly held up essentially by the "dodgy tradie" stories which are routinely passed around but get re-interpreted as "it's very easy to do <obvious stupid thing>" when the stupid thing is something like "don't do a wire run from 10 short pieces of wire you have lying around" or "PVC pipes need to be glued together to not leak".
