This would eliminate most the edge cases.
The problem is trusting the algorithm to make decisions and then pretending you aren’t responsible for them.
What you are thinking would apply if they were handling 10s of hours of video everyday from dozens of individuals.
They have about 10 hours of video uploaded every second, throught the day, all week, every month, every year... and their platform has 2 billion users. What you are suggesting would not be possible even if they hired everyone eligible to work in the world.
Youtube literally operates walk-in 'creator spaces' where creators with popular channels can go to make use of editing equipment and resources. They can staff a media liaison office. They can staff a media liaison office in every major city of every first world country. They have those offices already existing to sell adverts, after all.
It would be trivial for them to operate those media liaison offices and ensure that things like this don't happen. They choose to hide behind the 'oops, the algorithm did it, nothing we could have done' excuse.
