I only agree in one respect. That it's like finding the bad light bulb on a Christmas tree. Other than that, I disagree.

But you can be careless with UTP connectors and hubs?

So, what you're saying is that, with CAT-5 you don't need to make sure anyone trips over the network cables? Hmm. I've accidently tripped over a CAT-5 cable and snapped it right in half. Contrarily, I've bumped my coax cable pretty hard, and I almost pulled my computer system off the desk. The coax works fine. Even if it got damaged, it would take me 5 minutes with a standard wire stripper and pair of wire cutters to fix - with no crimp tool.

Relative to what? With coax, the cost of a hub is $0, so relative to coax, an 8way hub is INFINITELY expensive. Even $30 is $30 that I wouldn't have to spend. And I don't know where you people get your prices, but the cheapest 10Mbit card around here is $25 ISA, or $30 PCI for NE2000 clones. The cheapest 4 port hub (low end crap) I could find is an Acer for $50 + tax of 15%. An 8 port is $80.
So, an 8 port hub would run $80 + 15%, and I don't consider that to be "cheap".
Minus the cost of network cards, for the cost of your 3 computer network and a hub, I can put together a 10 computer or more coax network. That includes all cables and terminators. Network bandwidth is the same on coax as utp anyways unless you get an expensive switch, and then you're not talking $80 hub either, more like $200+. So the UTP is faster/better argument for a cheap network doesn't cut it. UTP is more scalable granted, but that is meaningless if it is unlikely anyone will need to scale over 10 machines anyways. Even then, one could plop 2 NIC's in an old stripped out 4Mb 386 box acting as a router in a closet, and have subnets. There is your scalability. Not as modern or nice, nor fault tolerant, but it isn't needed in a *cheap* home network either.
>and you'll save that much on <insert favorite >headache pill here> in short time.
I'd agree with you in a work environment where people tend to fuck things up pretty bad, but in a home environment it isn't necessarily the case. If you install coax, the cable itself is no more vulnerable to being tripped over, drilled into or otherwise damaged than CAT-5 is. Also a home network is unlikely to have a machine bring down the network, and if it did, it is only a home network anyways. If reliability and whatnot were a factor in a home network, then cost would be second to begin with, and coax wouldn't enter the equation.
We must realize that cheap-network means just that. $30 extra cost, is $30 that could be saved. And here, your $30 hub is $90+ with tax... That is real money to me. If we all had $200k incomes the scenario might be different.
