Have we completely eliminated any reign State-IP may of held over people's actual property in result of the creation and viewing of our podcast?
You shouldn't have any problems as long as you don't press charges on anyone, even if your license said that if your shit gets copied the perpetrator's first born son belongs to you...
There's nothing wrong with a license, which is essentially a contract. You simply can't enforce your contract on third parties unless they agree to the terms. If I sell you software but the contract says that you agree not to give it to third parties and you must sacrifice a chicken each full moon, that's compatible with Libertarianism. However, if you violate our contract and give the software to a third party, I can't enforce the terms of that contract on him or her.
That's like saying if I open a bank and take all the deposited money and hand it off to my buddy, my buddy get's to keep that money because, Sorry Folks!, your contract was with me, not my buddy!
