There is already a rule in place concerning this situation.
“BASE PATH - The base path belongs to the runner EXCEPT when a fielder is in the path attempting to field a batted ball or when a fielder is in the path and in possession of the ball. After a runner has been put out (typically on a force play at second) he has NO rights to the base path. If R1 is put out at second by a long distance, he must duck or get out of the path. If he is hit with the throw while in the path, or makes contact with the fielder who is in the act of throwing, while on his feet, he is guilty. Since he is already out, the runner being played upon is called out. Rule 7.08(b), 7.09(L)”
The catcher does not belong on the base path.
The rule you are citing pertains specifically to baserunners who are attempting to interfere with the play of infielders. It has absolutely no bearing on the catcher whose job is to place his body between home plate and the incomming base runner from third while the ball is being thrown to him for the play at the plate.
You obviously do not play the game..........
