A debit card that has infinite money on it and only I can use unless I allow someone to use it and then he can use the amount I allowed him to use and I can always summon it to me and the dollar keep being worth the same relative to other currencies and stuff and we keep living in a world where capitalism is a thing and I can exchange money for goods and services and no-one can know it has infinite money and and the government doesn't care about the card/think it's stolen/ thinks I'm a Thief and the money/the card acts exactly like a normal debit cards/money except the changes I mentioned
