This game's about loot. For me it's potential is in collecting weapons, armor and gear. Not to forget ships, shaders and emblems. In the past 2 weeks I often was confronted with capacity problems and had to dismantle this and that to keep new stuff I earned. So why not increase the cap of our bank. If I wouldn't find any stuff and nothing new I could grind for Destiny would already be dead for me. But when it comes to the point were i'm forced to dismantle things i rather would like to keep the aspect of collecting is gone and out of my hands.
Please don't tell me I should create another character - that's not the solution.
