I totally get that size does matter in this case, but do you generate your own electricity? Do pump up your own water?
But we have farms on top of mountain sides that do not have roads, that have electricity and broadband. They follow the same path as the electricity cables, that is no brainer way to do it, if you do not want to spend much time on planning.
Also 50Mbps is not high-speed, which probably would be a super upgrade for a lot of people in the cases we are talking about.
Yes, UK has the same problem, which is why I think it's more a systemic issue of the country and not an issue with size. Regarding Romania, I spent some time there 5-6 years ago and there are probably many small towns that have lesser service, but everywhere I went, they had decent internet, I spent most time in Targu Mures and other cities around. Then again I spent some time outside Munich about 10 years ago and that company had 2Mbps SHDSL link....
Deploying fiber is cheaper to do in rural areas than in urban usually. My grandmothers house on the coast far away from everything, got good 4G speeds.
Sorry about the mini-rant, I would think that the powers that be, would want people to have internet.
