Making professional movies is a full time job.

Sure, and one whose economics could be supported without made up rules about how to exchange information that can be copied for free. That is what I claim.

In other words, I believe artists and drug manufacturers alike would still find ways to fund important work even without intellectual property law or secrecy of information.

Yeah movies would be reduced to commercials. Commercials are free after all, so that proves it is possible. So we would probably still have movies like Transformers and Star Wars, so I guess geeks would be happy.
