I'm assuming that #5 is limited by the space in your pockets/purse and would only trigger if and only if you owe a debt on something to someone within your visual range. Additionally they would need to speak to you verbally what exact amount you need to trigger the pocket filling.
Thus; you could not likely pull out amounts even exceeding a few hundred thousand without some really clever planning.
I'm also assuming you will never simply pull a check out of your pocket, this superpower is CASH ONLY, which burdens you with the advantages and disadvantages of cash.
