At least in the areas so rural that the power companies didn't want to build out infrastructure either, where electricity only became available after FDR's Rural Electrification Act formed non-profit local electrical coops, the problem can be solved by allowing those still existing coops to get into the broadband business.

Mississippi changed the law to allow this, and gave out matching block grants to get the ball rolling, and has seen great results.
