Get out of here. First, show me the law that states you can't turn your entire estate to powder and spread it across the ocean. There may be some enviro laws that might cause a problem, but the state can't stop you.
People die all the time who hate their relatives, and frankly people in general. They don't leave anything to anyone, and they don't want the government to get anything more than they deserve, so they make stipulations on what to do with the stuff they have. I'm talking about people who have millions of dollars in assets. The estate pays whatever death taxes are due, and an executor, usually for a fee, since someone has to do it, makes sure the decedents wishes are carried out.
