The water and electric grids in my city have near 100% uptake, especially in the denser parts of the city. While in most cases I would agree with the uptake analysis (eg, if we were talking about coffee shops), I'm not sure that it applies to the particular case of talking about rolling out a government monopoly in place of a natural monopoly using city bonds to cover the upfront cost (and time to smother people not using the city network). Further, I was actually just interested in plausibility: I didn't account for growth rates, the attractiveness of a city wide network, competition between ISPs, etc. That the answer was ~100 and not ~10 or ~1,000 is interesting to me, because it means that even if the technology isn't there, that the details work out a lot closer than I was expecting -- expensive, but not impossible. tl;dr: Deciding if we should roll out government infrastructure isn't quite the same analysis as seeing if a business works, and I only did the latter as a proxy for plausibility.
