Also, when we queue up for a roulette, the last thing we are thinking is, "Wouldn't it be great to spend half of my play time watching the same cutscenes every single day?" ...so really like someone else said, if we separated those players from the newbies, the newbies would be queuing for hours on end.

If the cutscenes are so damn important to people, I don't see why you are running them in a PUG. Go find a nice, friendly, casual free company that's willing to do private FC queues of story content. Otherwise accept that the VAST majority of people in those dungeons are not interested in making a production out of what should be a 20m run at most (and I've done both of those in a decent group within 10-12 minutes).

The honest truth is very rarely do we see the obnoxious white knight attitude in those groups, and most of them will speed run with or without the new player skipping. They still get credit at the end, and they're able to progress in the MSQ.
