If you live in Urban areas, you expect to have Water, Electricity and sewage pipes as standards in building. Why cant you add Fibre to that list? Standardising Fibre in the building and ISP only gets to FTTB. Effectively making it like DSL.
Of course, there is nothing stopping local governments from forcing broadband into new construction... It just isn't on the same level as water / sewer / electricity.
Zero electricity invites excessive use of open flame, creating fire hazard. It is at least part of why going off-grid is difficult unless you are deep in the country in s state that isn't too hostile to it.
It could be used for safety, but at the individual level, not at the community level.
