The problem you mention is essentially that people with more money and business acumen (here: social media companies) will leverage said money/business acumen to make even more money (here: promoting videos and reaping virality-driven ad revenue). They will amplify their initial business advantage to outcompete those skilled in the subject-matter work. Under capitalism, it's as often considered a feature as it is a bug; which one it is in any particular case depends on how popular the people getting outcompeted are.

Hindsight is 20/20, but to me, copyright law looks a bit like an ass-backwards, cart-before-horse approach. It's the legal equivalent of "solving" SQL injection by adding a client-side validation that prevents users from entering ' and the word "DROP" in their form fields. All it does is inviting exploitation.

Instead of making ridiculous kludges that end up benefiting those they were meant to curtail, perhaps we need to figure out a proper solution.
