Well my reply elsewhere in this vein seems to have been flagged to death or something, but.. OK. If its really just that, then yeah I am guilty of expecting maybe a little more intellectually here then is apparently warranted. Thanks for the help there.

Very modest opinion from a, as you can see, pretty dumb guy: the reason the Ring of Gyges is a "good" parable (or insert similar here) isn't because it somehow contains everything we want to be "argued" against, e.g., Thrasymachus. Rather, it's because it creates a unique ethical dimension to be interrogated and possibly overcome. It creates a true dilemma and a kind of need for ethics. OP's little story here just feels like Tlön, Uqbar, Orbis Tertius dressing on top of some commitments we are already supposed to be in on. It does not really inspire one to dig deeper, or to even really think (which kinda has a fun irony to it relative to the story).
