I think you mean "20 years after you die". That seems like a perfectly rational way to deal with people who want to be buried in their gold and jewels in a pyramid.
I don't, but, I mean, when someone comes and takes some of your money, then it means you had a fixed term on owning that amount, which just came to an end.
"Stuff taken away" is "stuff taken away", no matter what angle we take.
