Yes, but what makes it so weird is it's one pie. Like, imagine you made up "hacker dollars", which you can make more of whenever you want. They're sticky notes with a number written on them. Then you lent "hacker dollars" to yourself, at a 4% interest. So borrower you creates new "hacker dollars" to pay the lender you interest. If you wanted, you could just say that you forgive the loan you made to yourself, and pay the "hacker dollars" directly. If anything, it seems like a complex accounting system more than anything related to credit card debt or mortgages.
