You've outlined one of the worst aspects of it: Astronomical cost to cover the few percent of people who choose to live a long way from major cities.
One of the advantages to paying 5 times as much to live in an urban area than in the country is that services are much cheaper to provide. I've even thought about that choice myself. I could live in the country, where housing is (roughly) 1/5 the cost, and everything else (e.g. broadband) would be far more expensive. That's a choice people make.
Rolling out extremely expensive broadband to users in very low-density areas is, I believe, totally unjustified. If people want that lifestyle, it's up to them to pay for the costs, not to be subsidised by the rest of us.
