Special kudos to deisik for taking the impossible devils advocate position in this thread
However, lets not get too carried away.
So do you have any questions to the fiat model itself? I don't quite get your point. The fact that it can be and is heavily abused doesn't in the least take from the fact that it is the best monetary system in existence today from an economic stand-point.
I lolled!! It is tough to match that statement but I will try:
Shooting yourself in the head is also the best way to extend your lifespan from a medical standpoint.
Or how about: letting somebody steal your coat is the best way to keep warm.
Then you have to deal with the fact that people during the last 100 years have become much richer overall, despite all the fiat floating around since then. Otherwise, you will have a hard time proving that "for more than 100 years fiat has been a parasite living off people across the world"...
Since becoming richer and better off is surely not something you would expect from the victim of a parasite
It is certainly off topic but I'm still interested in what you might possibly mean by "people have become much richer". Perhaps a reference to improvement of infrastructure on global average, e.g. more running water, or technological progress? Clearly the population has hugely increased, meaning that individual's fraction of ownership of the whole shebang has gone down. Of course none of this has anything to do with being robbed blind due to stupidity of accepting counterfeitable dimensionless tokens in exchange for labor but I am still curious what metric you refer to which has increased in 100 years.
Irregardless of your metric, this is hardly an argument in favor of rule-by-counterfeitters.
Consider a similar argument:
"I've been slamming every finger hard in the door every morning since I was 6 years old. Now I'm 12 and look how much taller I am! Everyone should slam their fingers in the door. So successful!"
