At the same time we have not yet eliminated scarcity in other areas. Thus some still need digital scarcity to solve their physical scarcity. If physical scarcity in general was solved issue there would be no need to lock down digital media.
My gut tells me that elimination of scarcity is going to be a piecewise proces, whereby each step is countered with a lock-in of scarcity rules.
My gut tells me the probability we make it to post scarcity without a calamity (probably human manufactured) that ruins our ability to progress to post scarcity is pretty close to zero.
