You sound like someone who never bothered to make profit. And gold sinks(because the "tax" money doesn't go anywhere, it disappears forever, therefore you cannot call it a "tax") are meant to ensure that the amount of money doesn't go out of control, not to discourage people from trading with gold entirely.
Capitalism is the theory of completely self-driven economy, where the drive to "make profit" fuels the profiteer's motivation. So capitalism has no place in this marketplace, because everyone dislikes losing a lot of money due to 5% tax, and this leads to a crippled supply of offers requesting only gold. Maybe I should start dealing purely in heirloom points with gold to sweeten the deals. 
Bjorn you have to understand that in any game providing a marketplace like that there is a taxe which disappears forever. There is two reason for that:
1: The lose of gold through market exchanges create a hole in the economy of the "players/game" and therefore prevent inflations, remember before the taxe a loompoint where worth 700k now it's 500k
. It's better for new player and promote c-rpg gold farming.
2: It nerf the wholesaler <= (not native english here, not sure if it's the right word) who could before make profit from selling and buying +3 looms too easely. A bot could become rich in no time before the taxe, i would probably have done one if there weren't taxes
