Cryonics at its cheapest costs $1250 for a lifetime CI membership plus the recurring life insurance payments.

The membership is not even the costliest part. The insurance costs you a hard drive a month or more, and per Kryder's law and general consumer electronics, the disparity gets worse every year as the cost of lifelogging drops like a stone. Alcor runs at an annual loss and by definition is underpricing its services; I suspect CI is. Inflation is a major issue which will push up prices much higher than they currently are, which is what the current wrangling over 'grandfathering' is about - people have bought far too little insurance.

tl;dr: cryonics is more expensive than lifelogging. Cryonics will only get more expensive; lifelogging will only get cheaper. You do the math.
