I understand this approach, but I feel like the worry is balancing the cost of the items with the limit of the currency you can carry. The currency has to be WORTH something in order for an item to have value or be expensive, and removing the cap would promote play, but not engagement because then what is your playtime WORTH?

If I play now its worth nothing, I get no xp, in many cases if you have already looted a box, you can't loot it again, so the play time is actually less valuable now then if we could continue to earn items when we play regardless of parity which Bungie wants us all to fall under. Resources lets bungie control our play and habits. Without that control players could earn what theyu want, play how they want and be rewarded in kind. Are you really trying to tell me that there is value in have a cap on materials so the items they purchase have even more value??
