> It ignores the fact that humans progress by division of talent and labour. You wouldn't apply it to physicists, engineers, medical specialists, lawyers, politicians, financial experts, sports, or software developers. The key point you're missing is these people are selling their labor (aside, maybe, from software developers who could be selling their product). If you get an engineer to design a bridge they do the work and get paid, no IP rights, no "limited" monopoly, no nothing but a paycheck. If you get a musician to write a song for you they (and their heirs) get payed for that work for a long, long time. I understand where you're coming from (that artists should be a protected class so we have "enough" artists) but the days of the billionaire rockstar is probably over.
