Gresham's Law is an economic law with a moral foundation.

Bad Money is dishonest money - scrip, fiat, FRB, etc.  So, like all lies, eventually it gets found out.

What happens when lies are exposed?  What happens when people realise that they are being stolen from via the "money" they have been forced to use?  What happens when they not only come to the realisation that their wealth is being stolen, they also come to realise that there is an honest option?

Bitcoin adoption by long term HODLers is driven by these realisations.
