You are wealthy, in my opinion. Your items are currency; you just value them higher than other people. But for all items, there is a pretty well-accepted value that you could quickly and easily exchange them for.
Adding extra rares and uniques does NOT remove value from the system - it adds to it! Think about it. Say there are two neon deer masks in existence, worth 2,000,000 each (street value). Derrick creates a third one and drops it near Brit Bank. Now there's three. While the value of the original two would go down, the value of all three of them is going to be over 2,000,000.
Adding items reduces the value of existing similar items, but it always has a positive non-zero impact on the total shard wealth.
Otherwise, you could just solve the inflation problem by simply dropping a ton of gold into the world

EDIT: sorry, I was unclear. I'm not discussing this any more.
