I dont think this is actually true? You can, namely, write a will. You can choose what is done with your possesions, presumably including destroying them. Iirc there's a rule called the law against perpetuities, where you have control over your estate via the will, maximally until some time after the death of a specific named person who was alive at the time of your death. (which I find a strange stipulation)
