I don't think the judge has the power to move the obligation to JPM. The reason the Plaintiff attorneys are arguing we are creditors is as follows: To use the car analogy, if the new owner of the house took the antique car and sold it, then our claim would be a claim for damages against the guy who sold the car e.g., we are a creditor of that guy).
BTW, I have been considering writing something similar for a while. Thanks for actually doing it.
