It's not hard and I understand your point, but you have no control over what happens after you die. You know that your wishes may or may not be respected, so destroy/encrypt what you don't want to be seen by others while you can.
In any case, it's only a problem for the living. Dead you won't be bothered by it.
I find it more entitled to expect that "property" is a concept that transcends society's needs. Personally I require that my private collection of Picassos is burned upon my death.
