Yes the existing trade system plus making the Token a cash shop only item can stop a major flow of real money to in-game silver.
Players who needs silver in-game can sell other items through AH, because that is the original design of the trade system they have now. Enable Token trading just screw it over for us and IMC, since token gets used as a substitute for silver.
The point of making Token a cash shop only item is to eliminate ways that RMT sellers can transfer silver to their buyers, to make it difficult and not profitable for them to keep operating, which is the goal. It may not stop 100% of the RMT, but it will stop most of them, which I’d gladly buy a Token monthly for that.
