Exactly; and if a bodyguard can go hands-on at that level without a clear threat, why can a public figure not act as their own bodyguard?
I do wonder where it would go if the bodyguard pushes and the fan stays firmly rooted; how far can they escalate without an actual threat before the guards start getting arrested? One of the aikido instructors I've studied a bit with is a pretty solid guy to start with, and when he's being the uncooperative uke to force someone to find the right way to do a technique, you might as well be trying to push a granite statue around.
Since this is APS and thread veer is required. I've wondered similar to this about protesters blocking an entrance to a public building, place of business, sidewalk, street, etc. Shouldn't I be allowed to move them out of my way or have police immediately move them out of my way if they are blocking public travel? Why do we put up with this behavior? Sure they have a right to peacefully assemble, but that doesn't trump my right to freedom of movement in public or private spaces to which they have no ownership or permit to occupy. If a celebrity or politician was being blocked in many cases police or bodyguards can and will push their way through, shouldn't I have the same rights?
