A massive number of the people that live in rural areas are not providing food and key materials. In fact, the amount of farmland and farmers has been declining for years due to increases in agricultural efficiency (green revolution).
I've got no problem (to a point) subsidizing infrastructure for farmers and other key jobs, but acting like all of these people who insist on living in an incredibly unsustainable way deserve to be subsidized is ridiculous.
Does that matter? Not really. Infrastructure (Internet counts as that) should be available everywhere people live. Who knows, one day you might be in such a situation.
