Termination is basically a non-cost anymore. The price a pack of 10 sc/apc field terminations (IE that a random DIY'ers could do) is <20 bucks, and to your question, the same as a price of a pack of 10 ez-r45 connectors.

The loss and ease of mechanical connectors has gotten good enough (0.15 db or better) that most of the folks i know will only fusion splice when they really have to.

I agree it wouldn't make sense to do single pair or single fiber, but that's the actually the comparison at which 10baset-1l is at all competitive.

I have buried a lot of fiber, and a lot of network cable over the years :)

I was just trying to be fair and present the best case for 10baseT1L

In practice you can do 12/24 strand fiber (or 6 strand fiber + power + whatever) for less than the price of whatever particular set of 18 awg twisted pair (which is what the spec requires at 1km) + other things you wanted. The cable would be smaller, and if you use A3 or B3 fiber, it would be more flexible/support a lower bend radius than the 18 awg twisted pair. By far. IT's not even close.

This product is a special service product for private line service within a facility, likely over existing cable.

There are reasons why copper and coax exists though, which is what I was pointing out.
