I understand the restriction in trading is annoying if you want to help your people but it is also the main reason to promote RMT. However you can party with your wife to go farming and direct loot into her pocket. Trade restriction is annoying at first but it is good for long term. During OBT of ToS, getting a decent gear was hard so trade restriction at that time was not useful. Now you can get HG gears everywhere. Trade restriction should come with the ability to repair potential to prevent breaking gears as well. So that your wife can use her broken weapon to farm repair material instead of trying to get another weapon from zero. I can say if trade restriction makes you and your wife quit bdo then RTM and bot make a lot of more people quit this game.
Anyway, even you and your wife don’t like and quit bdo, it is still one of the most successful mmo in market atm with extremely high number of players…
