I disagree with you, if bungie implemented a trade system this game wont have the taste of getting a gun that you/i were grinding the game for 1 month or so, it will be not addicting to turn on my xbox do everything i can in the week before refresh trying to get my gun, and after you get the gun you were grinding for, in my case gjallarhorn, you feel the joy of getting the thing that you wanted for a while,(when i got it i laughed for about a whole hour while my fireteam telling me how lucky i am xD, its just that joy that makes me grind the game, ( i cant wait for hawkmoon to be available so the grind starts), plus u will get exotics easily and there is no point of nightfalls and raids except for entertainment, but on the other side a trading system would open a whole new window for people to enjoy the game if you like business, but i stick with my disagreement
