No it can't. It's just one of those 'what if' things, where in the case that someone actually does find a way to disable saving, he would crap-on the add-on and probably protect some of the save functions.
Theoretically, if he disabled certain client side functions and methods, specifically those that get the details of individual bricks, he could disable client side saving, or enable it by reactivating them. It could also be set up as the server's decision, for example, by making it impossible to get the type of brick from a ghosted object, and retrieving such information by requesting it from the server.
However, through scripting, yeah, it's doubtful there is a way to do this, and there definitely isn't one he can't make impossible.
It would be nice if people who knew how to script didn't try to break the principles of the game, or design scripts to exploit and abuse the game, because that just leads to less modding functionality when Badspot disables things. We can't change the names above the heads of players or bots because some jackasses used it to impersonate other people.
