What these people are suggesting is a central bank that Toribash itself owns and operates, similar to an existing bank. The problem and main difference between a real bank and this suggestion is that there is no easy way to verify the loaner's identity, let alone the loaner establishing good credit so that the bank can trust them with a loan. Furthermore, it would be nigh impossible to enact a good way of enforcing the loan. Yes, they can IP ban, but then that person gets another computer and does it again. No authority will get involved since it's a game, and it would likely be an international issue, and this would be small beans in comparison to other, real international issues.
