I'd oppose this issue. If they're dead, the cryonists of the future would have to be gods, magicians or complete wackos to be able to restore them to life. Someone would have needed to discover the Fountain of Youth. Every single under-developed country would need to have good healthcare so that their poor dead people aren't lacking in health when they're revived.

In the meantime, many of the frozen dead would melt thanks to global warming and the ineffectiveness of all the Kyoto Protocols in the world. If that ever happened, it'd just be kinda...nasty. Let's not forget that huge expenses will be incurred, for something that will never probably happen in the proprietor's lifetime. I don't think it's worth it.
