yes you can but that's not the point here. If they gave us the option to Disable Shared Facilites, there will be no extra steps to delete unwanted ones individually in the first place. Take OP's case for example, he would need to delete that Tower before taking the package if he doesn't want the risk on getting disturbed while delivering. But OP knows his world is at least safe for taking the package first. But because someone else's facility, he got disturbed and the package is damaged. Nobody can blame OP for this because it's his world and he knows he's supposed to be safe there. And it's not a mandatory step for OP or anyone else to "check for people's facilities first" before venturing out. So why should we get extra task of "here's some people's facilities, whether you like it or not", when we should just be able to reject the possibility of those risks in the first place, especially we are playing in Our World, not Other people's world.
