DWDM tech improvements have outpaced nearly every other form of technology growth, so the same single pair of fiber that used to carry 10 Mbps can now carry 20 Tbps, which is a 2,000,000x multiplier. The same somewhat-fixed supply of fiber can go a very long way today, so the price pressure for access is less than you might expect.
Noob question, is there an in-between where people sell spectrum bands on a shared fiber without going up to L2? Or is that just too complex compared to using off the shelf ethernet and sharing that.

I think these days folks say "dark fiber" for any kind of connection you buy. It bothers me too.
I meant a “single mode, non terminated fiber optic cable from point to point”. In other words, your own cable without any other traffic on it.
A shared one will be metro Ethernet in my parlance.

Yep, absolutely, often called "wave/wavelength" or "lambda" service, or "lit fiber".
