Do you have any idea what you are talking about? People are currently spending 500m and getting 10b items. It's not a one-off and some of items which were the rarest (prior to boxes) are coming into the game in multiples on a daily basis. Mystery boxes were not designed for people to profit off 90% of the time but rather a gamble where you profit 10-20% of the time. Also, most of the items in the boxes have the same rate, e.g. blue partyhat has same rate as dragon warhammer or an arcane.
