> What exactly made it possible to get copper wire into effectively every house in the country?
Subsidies.
> making sure people in rural counties are getting modern infrastructure
Sure. This is inefficient when an alternative is more than sufficient.
Again, I live in a rich rural community. I have gigabit fiber to my home. I have neighbors ditching wired internet for Starlink because it’s cheaper and good enough and they can also put it on their truck when they travel.
My property value does well from the subsidy. But it’s inefficient.
