Because "negotiating" the blank check that you already signed does't work. Yes, it works if they have actually stuck you with a bill that exceeds your net worth and expected income, but in that case you can't afford and/or don't need a negotiator -- you just default. It also works if you've stirred up a media frenzy, but you can't turn that into a business model for obvious reasons. The only place it does reliably work is in the imagination of those looking to downplay the severity of the current state of affairs.
