The answer is not simple. Your solution means small creators are even more disfavored than they already are by trolls stealing their work; trolls are already heavily favoured because small creators must dox themselves to file a claim, and now you're adding in payment burdens too. Any amount large enough for a corporation to care about at all will be too large for an independent creator. Now not only trolls but corporations have an incentive to steal from small creators, because small creators will not be able to defend their copyright, essentially granting it to the corp for free.
The actual answer is to tear the entire fucking system down because it only exists to serve megacorporations, and start fresh, but there's nothing simple about that.
