None of this is that daunting if you're living in a world with the sort of high demand for low cost access to space that SpaceX (right or wrong) predicts and requires for all this to work.

And if your barge is catching and returning 100 first stages per year, storing enough cryogenic fuel to get them back to land seems reasonable to me.
