Ah.. I missed out on the governance part. In that case, does it make sense to increase the cost of generating a new card + governance token as more cards are minted? Somewhat like a bonding curve? But most other bonding curves I know will allow minters to sell back the tokens.

As for the copies, if cost of subsequent copies are paid to the owner then perhaps it makes sense for the owner to be allowed to set the price? If he/she sets it too high, nobody will buy it. If set too low, then he/she misses out on the profits. This will make it more market-driven in a sense.
