Yes. Because I'm asking the question who decides what is involuntary or not. Who is it? It seems like there is a presupposition here, but who is defining that?

Coming back to the Tourette's example: let's say someone starts shouting cuss words and loudly annoying everyone else "involuntarily". Do they get kicked off the plane? Why or why not? Who decides that? Does the person have to present medical evidence that they have Tourette's to not get kicked off the plane? If so, can they also present medical evidence of a condition that causes them to spontaneously press play on their mobile devices with no headphones and would that be accepted?

I'm obviously not defending the behavior of the loud-music-on-plane-players, or advocating that everyone needs to smell everyone's farts. I'm pointing out that this is something that is arbitrary and weaponizable.

You don't understand that a phone isn't a part of the human body? Seriously? We as a society can't even come to agreement on that basic fact anymore?

If someone shoots a gun in a crowd is that too an involuntary bodily function? Is the gun not just part of their body? Are you confused by that as well? Where do we draw the limits on what is the human body? Who decides that? If I lay on the ground does the whole earth become my body?
