* I pay $10-25 for a movie
* I can then personally view that movie with myself and my family on the display I want (the last hotel I stayed at didn't have a HDCP compatible TV so I couldn't display my purchased film on the TV)
* I am not forced to watch advertisements or piracy warnings before the film
* I can put the film on other devices I own to watch via more convenient methods (my phone, tablet, home theater setup)
Are those requirements fundamental to having a legal system that protects the rights of copyright owners? Honestly I don't think they are! Because the DRM schemes that enable the above situation clearly aren't stopping pirates in the first place. But who knows, maybe there's an alternate universe where content creators allow all the above bullet points and – as a consequence – very few entities invest in creating art! In the end if I had to choose between that universe and the one we have today, I'd still take the one we have today where art is legally well protected enough that we have a plethora of it.
