You could spend all days coming up with possible reasons for not defrosting cryonics patients in the future. However you need to remember that no matter how low a probability you assign to your successful defrosting, this will be strictly greater than the probability of successfully being alive in the future if you go with the default, non-cryonics option of irrevocable destruction.

Ay, me... so little confidence in reincarnation within HN ;)

"The body of B. Franklin, Printer (Like the Cover of an Old Book, Its Contents torn Out And Stript of its Lettering and Gilding) Lies Here, Food for Worms. But the Work shall not be Lost; For it will (as he Believ'd) Appear once More In a New and More Elegant Edition Revised and Corrected By the Author. " --Benjamin Franklin (self-authored epitaph)

If instead of investing into cryonics you invest time, effort, and money into extending your life span by one year -- that would increase your chances of living long enough to have life extension technologies developed. The chance of it is small, but still much better, than almost zero chance of ever surviving through cryonics procedure.
