we would end up with an Austrian fork and a Keynesian fork dueling it out
Aptly put.
Perhaps the (roughly) two camps could agree to a 'velvet divorce' enforced with some social agreement and crypto-magic.
Gavin's Keynesian fork, with its inflated transaction supply, can continue its futile quest to mimic Visa, Mastercard, dollar bills, and pennies until the UXTO buffer pukes blood.
Satoshi's Austrian fork can continue to represent a new store of value and settlement system, guaranteeing for the first time in history every human the opportunity to be their own bank.
My stance is that a store-of-value that can't offer anything for the micropayments of the fledgling Knowledge Age, is going no where in terms of network effects.
Bitcoin is going to monopolize network effects in the NWO paradigm that most of the masses will fall into. If you are going to create an alternative, then you must identify the unique network effects of the alternative market.
