Let's imagine implementing Cohen's vision for a minute: each piece of content on YouTube must be reviewed by a moderator and be rated according to MPAA standards. By some estimates there are 2000+ millennia worth of videos on YouTube. Some significant portion of this is algorithmically generated or duplicated, but let's suppose 10% of it is new original content. 200 millennia is equivalent 1.75E9 hours. Suppose a content moderator earns $3/hr and no benefits and watches videos at 2x speed. To rate all the content, it would cost $2.6B. Not actually that infeasible. Society might ease the burden on FB by making a law that videos only need to be rated after 1000 views. Frankly I'm not sure this would be effective because of the lawlessness of the internet and the ease of moving information, but it doesn't seem impossible either.
