I don't care if I die - nor will I care about it after I'm dead, obviously. However:
1) Death is only the extreme. One can become unable to work for one reason or the other for weeks or months at a time. I would like my enterprises to be operational and somewhat on-track if that should happen
2) If what I'm building is truly a citadel, then I want someone to have the keys after I'm gone. After all, I'm not building this only for myself and for my contemporaries, but (_potentially, at least_) for the generations to come

Why do you care so much if you die? You will be dead and cannot do shit about that.
Just because you "take care now" about your shit after you die, IT WILL NOT HELP YOU AT ALL AFTER YOU ARE DEAD.

Maybe you will came back later in the form of a cat. Would you care then what they do with your bitcoin or business? No.

Stop worrying so much. Live the life damn it! Fuck the rest!
And btw... that's why you get sick! STRESS is the mother of all illness. So stop stressing too much about "what will happen with my shit after I die...".
