One argument I can think of to sign up for cryonics sooner rather than later is to create social proof for your extended family. The idea of evading death by freezing yourself and awaiting future technology for a cure might be too outlandish for older people to seriously consider, and leading by example might ease that process. And while you perhaps can afford to wait for better procedures or evidence about efficacy of cryonics, your parents/grandparents probably can’t.
