As long as someone is buying plex, there's income. Buying and stocking up is no different than what most players have already done, which is buy 6 to 12 month subs. Which means that AC got the $'s for it, but that makes cash flow tight now.
The flip side that we're not really looking at is, what's the current in-game market for plex?
All my accounts are subbed for the next 10 months, so unless I want to just give AC money now for no particular reason, they're going to need to wait 9 months to see more $'s from me. On the other hand, with the new frieghter bots coming, I could use some NIC. But here's the snag. How much NIC am I willing to trade 9$ for, and who has enough NIC to buy it?
Eve's plex is in the billions, but Perp's economy isn't that advanced. Meaning, if I put 1 month sub up for 1 billion NIC, there are only a few players that would be willing to buy it at that price. If I was the only one, that would be OK, but lets say there are 20 other players wanting to sell 1 mo subs. If I end up selling that sub for 200m, that would discourage someone like me from buying a second one (like Alex says, making a couple 100m nic isn't that hard), but new players would find 100m a very helpful boost. I would probably even be willing to BUY plex at 100m.
This may cause some temporary inflation, but the NIC isn't being generated out of thin air, its NIC already in wallets, that's be redistributed.
The comment about communistic corps is valid too. There is now reasons for the individuals in those corps to have NIC for themselves, or for the corp to earn NIC to buy plex for its membership if it wants to really support the communistic model.
I would caution though, that the pure NIC sources (like plasma) would need to be revisted, since that COULD generate inflation as the selling price of plex would go up as players are willing to pay more, meaning more NIC in the market, and players willing to pay higher prices. Which leads to the only real downside, is that just after something like this is initiated, new players that DON'T buy plex would find the market pricing well out of their range for PVP gear. But on the plus side, it makes the market stronger for players that want to buy/sell on the market (and room for new players to sell items with less markup).
