Yeah, I wasnât trying to say that you, Trundamere, was taking it on a personal level, I was trying to say that this argument only exists on a personal (in the sense of single person) level of âthis player was mining 100 diamonds and now heâs mining 150â. To the global economy it makes very little difference.
With (random numbers as example) 500 players mining, say, 100 diamonds each (on average) in a day, in the public worlds, then the total diamonds that go into the economy every day will be 50.000, right?
Now if we move 5 of those players to a private world where they can in the same time mine, say, 150 diamonds each because thereâs no competition, but theyâre still limited by how much time they can play in any given day, and they still need to stop to get new tools, empty inventory, etc. So the only factor that is eliminated is âfinding a fresh area to mineâ, which makes it a bit faster, but not by a lot. Time to break rocks, actually find the diamond in the middle of all that stone, etc, that all doesnât change.
Weâll have 495 players mining 50.000 diamonds a day (because other players would mine the ones that the 5 stopped mining) and the 5 players getting 150 diamonds each would get a total of 750 diamonds instead of 500.
So for the players it makes a huge difference (50% more) but for the economy the change is very small (1.5% increase in total diamonds), and thatâs not really enough to affect prices all that much, but the perception of the individual blows it out of proportion by a simple matter of psychology, because a personâs first instinct is to think in terms of individuals (player a vs player b) and when they see that 50% increase for those 5 players, they tend to transpose that individual difference to the economy, and think of it as a 50% change in the whole economy, which is just not true.
So yeah, I was trying to make things shorter with the monopoly example (one player has more colored money than another but to the bank thereâs no difference) but ended up making it more confusing instead. 
Edit: I was trying to avoid the numbers, too, because even I got bored reading what I just wrote.
