I made the difference absolutely clear but it would have been better if I gave the Star Wars example immediately instead of messing about on Google. Let me give it again.
I looked up the production budget for the 1977 Star Wars. It was $11 million in 1977 dollars.

You said, "if we want entertaining movies, we have to have intellectual property laws".
Now you're saying, "if we want Star Wars, we have to have intellectual property laws".
Those are two very different claims. I'm not really interested in arguing about Star Wars because even if it never existed, we would still have other entertaining movies. You might be able to get me to feel torn about losing all forms of art unless we stomp all over personal freedom but the fact we won't have Star Wars doesn't even make me pause. I think The Lord of the Rings trilogy is an even better example to use on me as I love those movies. I think they are gorgeous, amazing, etc, etc. However, it's still not worth the price of admission, if that price is the loss of the ability to share information freely.
