I don't want to oversimplify the issue and don't disagree that everyone in politics would prefer if better broadband infrastructure just happened and all they had to do was show up and cut a few ribbons without investing any political capital. But I think you're being a tad disingenuous here. You are too smart and well-informed to buy this argument if I were to make it to you.
At the same time, I inserted the caveat of importing regulators from Scandinavia for a reason. Public infrastructure in the U.S. (outside of NYC/Chicago) mostly sucks and is poorly run. I say this because I've walked the walk: I used to commute on Metro North every day from Westchester to Manhattan, then on SEPTA from Wilmington to Philadelphia, then on Amtrak from Baltimore to DC, then (briefly) on the D.C. Metro. Metro North was fantastic, but the others are worse than Comcast.
The basic problem is that I don't have the choice to vote for Stockholm's fiber system run by Swedes. My only choice is between Verizon (which is actually pretty damn good in Maryland), or the same folks who run the D.C. Metro.
As a matter of personal ideology, I'd say: let's build a nationwide public system with a federal/state partnership, and import regulators from Scandinavia to run it. But that's not one of the choices.
