> Running low-voltage ethernet through an attic or crawlspace is within the skills of anyone with functioning limbs.

Except the whole point of his post was that he didn't know how to do it competently, there's no way he wants to enter the crawlspace, so has resorted to wacky workarounds.

So, no, it clearly isn't within the skill (or desire) of anyone, but many would rather resort to hackery and hubris rather than pay someone to do it correctly.

I'll counter that and say there's probably minimum wage coders in India who write equal or better code than you at 1/10th of the pay, certainly possible as they have two functioning hands.

I generally feel the same way having spent a lot of my childhood on a farm, but when I started adding up the cost of all the random tools I would buy (now that I can’t skip out to a barn with 50 years of accumulated tools) to complete a task, and the time for the multiple Home Depot runs/missed steps I’ve started to realize it’s easier and cheaper (in some cases) to have someone else do it. Though there are still some tasks I can’t help doing myself just because I enjoy the challenge, catharsis, or I just want done properly.

I realized that it is cheaper for me to pay someone do some things than doing them myself. Instead, I can either work or do something fun or more interesting.

> something fun or more interesting

I think that's the key point really. For someone with even a mild interest in this stuff, the task of running ethernet cables is very approachable and feasible. At that point the time spent on it is a plus instead of a minus, and paying someone else is no longer competitive.

Well... I retrofitted a whole UK house with Cat6A, about 20 runs, longest run about 25m. The walls were dot and dab construction so quite a bit harder than drywall, but a lot easier than solid. I had my electrician brother to help for a weekend to do the cable runs. It was an entire two solid days of work just to do the runs, and this is with someone with the right tools and experience plus me having already planned it carefully. It would have taken me a week to do it alone. After that it was a full week of evenings terminating everything at both ends and another couple of weekends filling a repairing the walls. Definitely not for the faint hearted!

Worth it, though, and would do it again.

You are not a professional at everything and you don't know what you don't know so things that seem easy might not be and in fact could have significant dangers. A person that does the thing every week is going to be efficient and knowledgeable. It also creates jobs and supports the economy. A lot of strong independent types are frugal and arrogant and self centered to the point of being a miser.
