This may be true, but I don’t see a plausible solution for this moderation, who is going to do this, what criteria will they hold? Deciding on whether or not something is fair use can take a judge quite some time, how do you imagine decisions like this can be made at this immense scale? And if you say just “let them upload less” then how do you decide what gets uploaded and what gets left behind?
The result of laws like this is not that the amount of content is diminished but the type of content. This will result in silencing of small independent productions doing fun creative stuff while the big cooperations will just keep flooding the internet with more and more content. It will make the internet into something more like the television, and less like the more participatory medium it is now.
