Graph the two of them and get back to me. I'm talking about the slope. I do realize that the total sum is basically trivial either way. But slope is an actual mathematical term and I used it as such.
If it's a flat fee for the first 15 or 30 years then it should take a lot of wind out of their sails.
If people start doing the math and saying "but at 60 years this is completely insane!" then just ask for a list of affected stakeholders that this would bankrupt. I suspect the only people on the list would be Disney.
