After all, it's completely understandable to be thinking only of oneself in a high-stress, unexpected, and possibly life-threatening circumstance. Including brief supportive reasoning reminding people of others' safety might have positive effects.
For example, on certain aircraft models with limited OH space, a number of luggage OH bins - especially towards the extreme ends of the cabins as that is where the FA stations are - store emergency equipment as well.

If you decide to lock the bins, then either you have to sacrifice OH space and reconfigure the bins to move the emergency equipment to exclusive bins, re-certify the plane (as it involves emergency equipment) and re-train cabin crew to never store any emergency gear in the other bins. Or, keep the bin configuration as it is, but don't lock the ones storing emergency equipment while you lock the others, and face a situation where pax in the extreme ends of the cabins - where emergency exits happen to be as well - can still get their stuff, which may encourage others to pry their bins open and lose a lot of time.
Federal and international regulations state than an aircraft with more than 44 passengers must be able to be fully evacuated in less than half of that - 90 seconds. Crews are meticulously trained for this, including practical tests. (My wife used to be crew on 777 and A380)
Anyone who would be thinking about it, already knows not to.
edit: removed "criminally" as it seems that this would be a civil case.
Smoking in the lavatories, or standing up and refusing to sit down when you don't want to travel with someone - that results in criminal liability.
There are also several cases over recent years where immigration activists have been standing up in a plane when they wanted to stop the deportation of criminals. Result is usually fines (a criminal liability) and maybe ending up on a no-fly list (which is then not a criminal justice issue).
"I have to say that if watching the safety video is so crucial and you can be escorted off the plane, maybe Air New Zealand should stop making 'Rachel Hunter ice cream ad' safety videos," the passenger said.
in reference to the the way Air New Zealand makes their videos with more an aim of going viral on youtube than getting across a safety message.
Their last video was actually withdrawn because people hated it so much.
