The classic legal example is the Rule Against Perpetuities (https://en.wikipedia.org/wiki/Rule_against_perpetuities), which limits how much control a will or trust instrument can exert over real property. You wouldn't believe the lengths people have historically gone to make sure their notion of "the right thing" happens for many years after they die.
As a sibling commenter said, if you don't want people to truly own your personal property when you die, then you should destroy it. Or consider giving it to someone else.
