Ability to see other player perspectives on realms

Let’s say you have a realm, and someone who plays on the realm with you steals your stuff. You don’t know who, and they could have logged in at any time. Sure, you could just go to a back up, but what if another person did a lot of work, and don’t want to lose what they did. If only there was a way to find out who stole your stuff. That is why I think that on realms you should be able to see other players’ perspectives. There would be a setting which would allow you to choose if you want to be able to see other players’ perspectives. If you toggle it on, then anyone who joins the world would have to agree to let the game record their screen. The OPs would be then able to go to a tab in settings where they can see everything that the player they choose did(in their perspective),and they can even watch live. This would allow players to spot hackers on realms open to other people and would also would allow the OPs to see if anyone did anything inappropriate. This setting could even be on worlds and servers, but realms would be a good place to start.
