Just a barf bag

Following the 8/10 discussion, some politicians now advocate that all hand-luggage should be prohibited on airplanes. What will happen if all frequent traveller scientists are no more allowed to take anything inside of planes? No laptop, no organizer, no paper to read, nothing to review, nothing to administrate? Imagine that the inflight magazine is only good for 5 minutes and that there are no interesting flight attendants anymore. Just a pencil and a barf bag in front of the seat. Would that revolutionize science?
