That part almost makes sense. Like, from the Bank's perspective your deposit is a liability, not an asset. But the mortgage on your house that they very much can give you is an asset for them and a liability for you. Two-column accounting works like that; everything in my asset column is going to be in someone's liability column.

But none of the other nonsense follows from that at all. It's the few sentences bordering on lucidity to make you forget how insane all the promises from earlier were.
