While that sounds great, I suspect that there are many people with the skill and interest to be professional artists who, if they were spending their days writing code or welding or $JOB, would be uninterested / unable to dedicate resources (time, money) towards Creating Things in the degree that they can when creating such things is their full-time job.
tl;dr: There should be a way for creative people to make Creating Art the occupation that pays them money for rent/food/etc.
There's also undoubtedly lots of interesting and potentially profitable art and innovation that is impossible because of those IP laws. I can't confidently say that one set is more worthy than the other.
