There's also the creativity angle.
Some of the best art of the twentieth century benefited from having limitations imposed on it, forcing the artists to get even more creative to sidestep those limitations.
As an example, look at films like the original Ghostbusters, Robocop, etc, which had numerous budgetary and technical limitations, but because the people involved were all passionate and devoted, they made something great, not to mention songs about drug use in the sixties and seventies which came up with clever euphemisms to sidestep FCC rules regarding depictions or glorification of drug use.
I've a pet theory that one of the best ways to help an artist grow is to put some sort of impedance on him/her, forcing them to be more creative to overcome that impedance and making better art along the way.
Nah, it's a good example, I just hadn't thought of it, lol.
