This is just one scenario, but you can imagine a system where the person who profits over any IP would pay IP tax, which would then get distributed upstream to previous registered contributors. IP producers would need to be tracked, but this is something that systems such as github already do extremely well, and credit card companies already run systems that process fees for every single transaction.
Producers will announce themselves anyway, in hopes that their content will generate as much value as possible. Contributors would announce themselves in exchange for the right to use any IP.
So say DJ Foo remixes a Michael Jackson song and uploads it to YouTube. YouTube will withhold the IP tax from the ad revenue paid out, and hand it over to the IP revenue service with the copyright profile. Michael Jackson will get paid for DJ Foo's remix automatically.
Say DJ Foo does an original song and uploads it to YouTube. The same thing will happen, but DJ Foo will get paid from the IP revenue service since the IP is tied to DJ Foo as the originator.
And imagine if all this information was open and public. We could lookup any product or work and see all of its activity and history as if it were open source code on github.
In exchange for everyone paying an IP tax, anyone creating anything or adding something will be guaranteed to get paid for their contributions based on the maximum value society can generate from it. Violators will be shamed just by manipulating the system because they'd be doing it in public, and it would be in the IP creators best interest to police their work and report violations. Violations don't even need to be criminal. They just need to be fines that disincentivise those actions enough, much like parking tickets. An example violation would be uploading someone else's song without changing it or false claims regarding ownership.
