With the help of his storied Knights of the Round, Arthur builds Camelot, the fairest kingdom.
But Arthur is manipulated into self-conflict, his personal desires at odds with the principals he must uphold.
Camelot falls.
Arthur was raised by Merlyn to be a just and fair philosopher king but, despite his best efforts, the Kingdom he built fractured as it grew, power blocs consolidating around conflict, driven by ambition and pettiness.
Also: it's admirable to be the change you want to see, even if you fail at it. Arthur is the once *and future* king, after all.
Satoshi is like Merlyn: a time-traveling mystical teacher. :) And, like Merlyn, Satoshi left.
But the key difference: Bitcoin has no King Arthur.
There is no one person or group (so far) whose power can be coveted, usurped, or broken.
The blockchain is itself Camelot. No King Arthur nor Knights of the Round (e.g. Segwit2x) required.
The desire to be a Knight and follow your King is in all of us but, as TH White wrote long ago, that way lies tragedy.
