That depends, in the case of the youtube video the creator, I believe, would make more as he could verify that it is his, however this is a hypothetical situation.

The reality is that the cheese grater is a curator for the OP, and his curation of that video would be paid out after 7 days. If the OP later comes to Steemit, it will be after the 7 day period, and to post his video then he will likely make more money. Additionally he would make twice as much from repeat youtube views.

The point that I was trying to make was that we want more frogs, let people post what they will post as long as they have the rights to post and link that content legally. If this system becomes more like a Reddit or Facebook because that is what new users are comfortable with and want it to be run that way, let the free market decide.

No one forces content to be voted on, as long as it is legal the free market will decide how much the work to create the post will be worth. It may not be worth much to you but to the followers that were exposed to it and upvoted it, it was worth something to them.
