Why does NO ONE remember the lawyer saying this!?

So many people here keep asking why they didn't just get a loan from someone else to pay off the debt to the bank. The reason why that wasn't an option is because midway through the movie their lawyer clearly says that Chevron WILL NOT drill for oil unless the land is DEBT FREE!

Otherwise they could of started drilling weeks ago and used that money to pay the bank. They had no choice but to buy back the land in way that left no debts to any other parties.

Also people keep asking why the Feds weren't involved and the reason is (which is stated in the beginning) that the banks they robbed were ONLY LOCATED in Texas. There were no branches outside of state line. Also the amount stolen from each bank was only a small sum of several thousand at a time.

I have to say for the most part I couldn't find any real plot holes with the story which is why I enjoyed it so much. They really did get fcked by the bank and had no way out.
