If there were no government or Friendly AGI doing it for everyone, I imagine it would chain backward through time: those still alive who are friends and family of the cryo-preserved would resurrect them. Then, those people would know older cryo-preserved people, and would resurrect them. (Unless, I suppose, the cost were exorbitant and the cryo-resurrected didn't have the means. But this is a future, post-death, probably post-singularity world; it'd probably be a society of abundance.)
