At some point they should probably be given an option to pay for issuance (before block xx) or relinquish asset rights ~
I believe that I brought this idea of subscription fees for the asset in discussion previously here:
https://forums.counterparty.co/index.php/topic,150.0.htmlI am not sure what the devs have decided, but the recommendation by Global_trade_Repo and by GLaDOS were very helpful.
It's my view that asset issuance will be hobbled by this 5XCP price and this will also depress the value of XCP as companies cannot build quickly enough on the platform.
