Not sure you're helping yourself here. The established movie industry uses its content rating system as a bludgeon against independent filmmakers. The video game industry's content controls are largely a joke, assigned arbitrarily by people who never actually play the game.
which are pretty much a joke. PG is now a worthless rating

The difference between PG-13 and R in many cases is completely arbitrary.
The ratings lump many kinds of movies together and says absolutely nothing about their content.
No movie can be NC-17 or unrated because that is a kiss of death. No theaters will play it, no big box stores will sell it. I think what R can get away with has broadened considerably because of that.
For example, here in Indonesia, if I buy eggs at the supermarket I don't really have to worry about them carrying salmonella. Why? Because truth in labelling laws and demand for salmonella-free eggs means that the farms that sell to the big food distributors all get tested so they can label their eggs as salmonella-free.
One really wonders why this hasn't taken off in the US. I can think however of a few reasons (it's not just too much or too little regulation but the wrong regulations).
At some level it comes back to regulation. It is part of why I feel bitcoin is misguided.
As a Distributist, my feeling is that successful regulation supports decentralization. The problem with the regulation vs deregulation dichotomy is that regulation is usually pushed as a centralizing power, while deregulation is usually also pushed as a centralizing power.
Because that has worked wonders for the other industries -- let's have pharma companies, oil, food producers, just self regulate.
