You are missing the point, that money spent on Rangers running costs, is of no interest to creditors. They want as a minimum as much as they could achieve by liquidation and selling off of all assets. They would consider the £3.5 Million as being due to them, not for ongoing expenses. It's like offering to buy someone's wallet for £5, and when he points out that he has £3.50 cash in the wallet already, you say that's fine I'll need that for my taxi home.
