* The Satoshi paper overcomes mining becoming less profitable and diminishing to zero by repositioning transaction fees as a future source of revenue - "Once a predetermined number of coins have entered
circulation, the incentive can transition entirely to transaction fees and be completely inflation
free".

Transaction fees are an inventive feature of Darkcoin which will remain once the predetermined number of coins have been circulated. Honest nodes are also encouraged to participate in DarkSend transactions by offering them the opportunity to earn additional fees charged against dishonest actors that attempt to deliberately deny services to the network. This feature creates a form of fee structure akin to charging for excessive email traffic in order to reduce the profitability of spam.

* It will also allow for a longer period of mining for CPU/GPU users.....This supports the decentralized nature of Darkcoin by making small scale mining feasible for a longer period of time. This discourages dishonest attacker nodes from accumulating more processing power than honest nodes and thereby improving the security of the system.
