That is definitely not an option for the vast, vast majority of people in the US. Doesn't matter how much money you offer, good luck digging up Pacific Street to lay a fiber cable directly from a data center to your mansion on billionaire row.
Your neighbor on billionaire row where most Americans apparently live will gladly allow you to tunnel under his land, I'm sure. Since money isn't an issue, offer him a billion or two.
I do agree with you though: saying money isn't an issue when looking for alternatives is absurd. You can pretty much solve anything by throwing money at it. "You have an option if you consider it an option to pay 10x or 100x the price" misses the point entirely imho.
It's not just your neighbors, it's the city, and the activists who know their way around the labyrinth of regulations (not all of whom can be bought off without someone else just taking their place).
