Where nodecoin becomes part of the fabric of NXT is if we as a community decides to offer it as an official ongoing reward to run a computer and support our network.
Once we do this, once we cross over this line, we can no longer call ourselves a pure Proof of Stake cryptocurrency.
We will have changed the core definition of what NXT is if the NXT experience is expanded to include the awarding of nodecoin along with the forging of NXT.
This is the key point of rj's argument. Nodecoin is not any "ordinary" coin anyone can create on top of Nxt. If it were, no one would have any reason to object to it.
Reasons why it is not any ordinary coin:-
1. It was designed to be used as an integral part of Nxt. At the heart of any crypto currency is the blockchain, and how it is secured. NodeCoin has been positioned to be the mechanism to (help) secure it. Anything, whose function is to secure the network will be seen as an integral part of Nxt, whether it is in the NRS core or otherwise. This alters, or at least can be perceived to alter, the DNA and hence the very identity of Nxt. Therefore it cannot be treated as just an ordinary coin anybody can build.
2. It is designed to power the key engines of Nxt (AE, gateways, NXTCash, NXTmixer, etc), which are projects funded by the community. "
Nodecoin should be redeemable for accessing services (DAC, NxtCash, whatever)". So if a Nxter has millions of Nxt but no NodeCoins, he has to buy them just to uses the very services that are suppose to make Nxt unique? That makes NodeCoins to be more superior in function than NXT.
Edit: I hope I have got this point wrong!
3. It has been positioned by James as a non-profit, community project. This gives further credence to Ricky's point that "we as a community decide to offer it as an official ongoing reward to run a computer and support our network". If this has been privately developed by James as a random Nxter, this association will be absent.
If we agree that it is
no ordinary coin for the above reasons, then we should consider Ricky's point about NodeCoin
altering the very fabric of Nxt; and not just brushing it aside as just a coin anybody can create on top of Nxt.
You all have to understand that it is out of our power/control to decide if Nodecoin (or any other coin) will be built ontop of Nxt.
. People will decide if they use it or not.
