Food for thought:
Quark - 247,000,000 QRK initially mined.  1,000,000 QRK mined each year after.  0.004% mined each year roughly.
Premine - 500,000 PMC instantly mined.  0 PMC mined each year after.  At 0.01 PMC tax per transaction, it would take only 200,000 transactions to reach 2,000 PMC which is 0.004% of 500,000.
Yes, I know it's not quite the same, but it should give you an idea that mining for TX Fees isn't that bad and it's similar to mining for Quark......kinda.
