Silver buying and trading will happen regardless of the blocks in 1:1 trading, and this is the proof: (image at the bottom), they trade the silver with the market.
I agree with the block in 1:1 trading for silver but it should be allowed to trade items, it’s only an hassle and cashgrab for normal players.
This doesnt support your argument on why you shouldnt block it. All it does is show that the RMT people had to buy into the token ecosystem too in order to do this since noone would buy items if they became untradeable after. Not to mention the item you get will be down 2 potential.
Also, you can 1:1 trade without a token it just becomes untradeable. So its not blocked.
