Your view of cryonics seems similar to the concept of reincarnation.

Also, some would find personal value in setting up another entity for success. Namely, anyone who has children, but also anyone who argues for the good of the next generation. Essentially, it seems as if you are arguing against giving birth to a new you.

While that makes sense in terms of prolonging your own existence, it certainly seems to land on the "evil" side of selfish. Not that that is a problem... just interesting.
