I happen to have fairly strong ethical opinions about the funeral industry.
How do I die and deny them any profit from my death? Bonus points for actually causing a net loss.
I live in the US, so at least one answer for this country is preferred, though due to the ethical nature of the question, answers about how to achieve this in any region are welcome.
If the answer is "figure out how to get Y law repealed before you die" then that's the answer - there's definitely not a "you can't" answer to this question!
