If you kill someone after they paid you a lot of money to preserve your corpse the courts might not agree with the assisted suicide bit if your body was still functional. They'd more than likely call it murder too.
I'm a firm believer in the preservation bit, I don't think it will scale and I totally do not believe in the resurrection bit. It's a bit like performing a magical trick where you smash somebody's watch in act one and you still haven't figured out how to do part two.
At one point, a court might have ruled that your usage of a cigarette lighter to be witchcraft summoning fire demons.
To use your analogy: You're getting on an airplane and the security guy says "no watches". You're now faced with the assured loss of an heirloom item. So you break it, and the guy lets you board. You figure eventually you may be able to reassemble it in some form. Like the Iranians did to the "destroyed" documents in the US Embassy there.
