Sure…but would you rather this not be the case? There is a pretty basic accounting identity out there called the equation of exchange (should probably the exchange identity, but oh well).
The equation is,
MxV = PxQ.
M is money,
V is velocity (how quickly the money changes hands),
P is the price level.
Q is quantity.
So, if players build more stuff over time then either M or V has to increase or P has to go down to maintain the equality. If the money supply is fixed–i.e. no more new ISK via ratting. Then that leaves V and P. Now it is possible that players could spend their ISK faster and faster, but that will likely cap out. So that leaves P. In other words deflation. But once deflation gets “big enough” we’ll likely see a drop in V too. Why? Because deflation means you are earning interest by not spending your ISK. If the rate of deflation is 10% per day, then by not spending today I have 10% more purchasing power tomorrow. Eventually this will lead to a slow down in Q too. That is, the economy will eventually collapse.
High inflation or high deflation are very bad for economies. Both virtual and real.
So CCP has put in place a mechanism to let the money supply grow. Now they have to be careful with various changes that the growth in the money supply does not exceed the growth in the real economy by too much, or that it drops too far below the growth in the real economy.
And the growth rate of the money supply is based on players trading time for ISK. Where bots are a problem is that they reduce the time cost side of that process. That is a player is going to rat until,
MC(player) = MB.
MC(player) is the marginal cost of ratting.
MB is the marginal benefit of ratting.
But a bot is such that the MC(bot) << MC(player). That is the player that bots will rat alot more and thus we’ll get a higher growth rate in the ISK supply unless botting is dealt with at least to some degree. Hunting and banning bots pushes that marginal cost back up and moves us back to a healthier growth rate in the ISK supply.
And a player that bots and RMTs is even worse in that the marginal benefit for the botting RMT player is higher than the player who bots for his own wallet and also the player(s) who does not bot at all. Thus, distorting the ISK growth even further.
Now, is PLEX RMT? Sure. But it is not like the above. If I buy a PLEX and trade it for ISK, that ISK still has to come from a player who faces the above trade offs in regards to his time and the benefits. There is no real added bonus to rat more in aggregate. Because without PLEX how would I make ISK? Well…ratting is one way. So if I am using PLEX so I don’t have to rat and another player is ratting to buy my PLEX it is far from clear that there is a net increase in ratting and thus ISK generation.
In other words, drawing an equivalency between CCP’s “RMT” and botting RMT is a false equivalency, IMO.
