Okay, I do it:

The forger:
 - has to have a client
 - risks all his stake if the client is malicious
 - risks his hardware if the client is not secured against malicious attacks
 - has to pay the electricity bill
 - has to pay for the hardware/renewal of such
 - has to pay for a place that hardware can exist in
 - has to pay for the bandwidth he contributes to the network
 - has to implement security measures (attacks, heat etc.)

I think there is pretty much at stake, literally.


So, forgers should be paid for their expenses. But nothing more or just a little bit of it.


As I said, I see forger as an equivalent to bankers with a most important difference (both keep the system running):
- forgers do the least what is necessary to sustain the system - verifying transactions and doing all the hard computational work
- bankers generate the drive to keep the system running by generating money and debts (watch the videos of freigeist) and therefore creating the urge of the society to drive forward, work and repay debts

Bankers have the unfair advantage of creating and manipulating the ways the system works. They therefore make profit at the expense of others.

Forgers can't and therefore don't. BUT they have to be compensated. The (compensation - expenses) should be close to 0 but maybe bit more to create incentive for people to join and explore the possibilities of NXT.
