No offense, but how often do you cross the United States in a car?
That said, here in Denmark it has taken less than 5 years to get to a situation where charging your car "at the pump" is about the same as filling it with diesel, calculated as price per distance unit.
Could someone try pushing prices upward in less populated areas? Sure. However, doing so will cause someone else to see a business opportunity and put up chargers close by. Wherever you have power enough to run a small business (like a welding shop) you have enough power to setup a couple of chargers.
Granted, this doesn't happen from day to day, and especially in the US it could probably take decades to get to that point, given the current political climate. However, personally I would not let two trips per year determine my choice of daily driver - I would save money on my commute and rent a fun car for those trips, but that is just me. ;)
