The last mile is not that expensive. Where I live you there’s provider offering fast internet to rural, sparsely populated areas and it’s not much more expensive than fibre I get in my apartment. I will be more expensive to connect a house like that definitely not thousands of dollars like they try to charge people in USA. In USA it would also be cheaper if the monopoly would not block smaller companies from rolling out the service. There’s a lot of stories about neighbours joining together and building the last mile themselves at fraction of the cost Comcast wanted to charge them.
