So, after reading Suzanne Vega's article about remixes of her Tom's Diner song, I was discussing IP law with JK and for some reason the fashion industry and its complete lack of IP protection (as a norm, they could use it) came up, and we further discussed magicians and chefs as two other IP industries that do not use IP law to protect their intellectual assets. I don't believe comedians do either.
So, no, intellectual "property" industries don't need robust legal protection for their assets.
