It is very irritating, I want to give my sims all their own private space which also helps to ensure they only learn the skills I want them to learn, getting exclusive access to those items.
But I don't think a day goes by without privacy being invaded, a sim somewhere entering a part of the house they should not be able to access. Often they are able to move back out when I tell them to, but sometimes they do remember they can't pass through that door when I send them back so then I have to unlock it first.
