I don't but again you are not focused on the law. As rehearsed in my previous posts, it's a tough path for a director to prove an infringement, but that does not mean it is a legal defect. And IP law is actually pretty clear, at least in the areas we are discussing.
Your "A lot of us" may be barking up the wrong tree. To me, the solution is not to fit a square peg in a round hole, but to create a square hole. An example of that hole is what's described in the article in relation to what Jerry Mitchell is doing. That makes a lot more sense as an expenditure of energy than trying to convince someone that the copyright law should be upended because a mass of ideas should be copyrightable.
