Gigabit is not important, remember when you could finally buy a 10MW electrical feed for your home and how much it improved your quality of life... Right that didn't happen because it is not important at all. Running 100W to homes means people can have electric light, 1kW means they can have motorised appliances, and 10kW makes cooking and heating practical... But 10MW? You had no need for it, so it didn't happen.
Likewise more bandwidth enabled applications only up to a point, 40Mbps DSL is perfectly good for watching TV and so on. I had Gigabit on someone else's dime back at the turn of the century and when I bought service for my current home I not only didn't enquire what it would cost to run Gigabit here, I didn't even choose the expensive 80Mbps option, I already know 40Mbps is fine. What mattered most even going from dial-up to 1Mbps DSL wasn't bandwidth, it was Always On. The Network's omnipresence is what matters.
Fibre matters to some extent for infrastructure, same way it matters what a bridge is built from. Fibre coms doesn't attract thieves, not subject to RF interference, lots of benefits for infrastructure projects, but Gigabit Internet for the home? Not important.
