'compressed' ? Why ?
And in general I would have said compression usually equates to stress/strain - you'd rather looking to minimise forces - or perhaps you mean a little pre-load to stop the potential for movement with vibration? (in which case why infinity over close?)
I've only opened up so many lenses, and managed to put back together less and it seems like you're in the real (actual!) movie making business so I'm keen to learn but I don't understand the reasoning as it's been put - probably a terminology/communication issue rather than lack of real world understanding ...
Ok, let's keep this simple. What happens with regards to the lens elements and groups of elements when you focus a lens towards close focus?
Answer: the elements expand away from each other to where sometimes the lens itself grows physically longer. Thus there is more space between the elements. They are suspended away from each other thus becoming less stable, structurally. They are less protected.
Conversely, what happens with the elements when you focus the lens to infinity? It's the exact opposite. The elements retract toward one another compacting less space between them thus more protection and less suspension against damaging forces such as vibration. The lens becomes mechanically shorter.
And just to clarify, I only bubble wrap and strap the lenses for shipping purposes. I honestly don't worry about hand carrying them on board the plane. I'm usually shipping several tons of camera gear at a time and it all goes into a pile. On a day to day routine however, I always store the lenses at infinity and wide open in the lens case.
I hope I didn't create confusion.
