The writer was talking about the people who produce original content.

He's asking: what if the guy making a youtube video of unboxing his new laptop couldn't use The Final Countdown as his soundtrack?

He still wants to upload his unboxing video. He still wants a soundtrack. What does he do? And what effect will that have?

There's no for-pay alternative unboxing video with a properly licensed The Final Countdown. And there's no for-pay system for him to acquire a license to The Final Countdown. The song isn't even the point at all. If there's any hassle involved in using it, he just won't. Not when he can just grab some JoCo and be done with it.

And if the creators do find and use permissive-license content, doesn't that necessarily erode the value of strictly-licensed content?
