No matter what regulations you add, there is no need for trading in Destiny, and it will only hurt the game in the long term. People will get everything they want faster, and will go find something else to play. Then, they won't care when new content is added, due to how long they've been away, so lost sales, and the player base will simply dwindle faster and faster. The more Bungie is able to keep people behind the finish line, the more they'll be able to keep extending the race, and keep getting money from us. The instant a shortcut is thrown in, Bungie loses, and the rest of us lose as a result.
