a world where people can be and are being revived is almost certainly one I want to live in.

Exactly, and that's really well stated. By being cryo-preserved, you're self-selecting for worlds where there is a high likelihood that

(a) contracts are honored (your resources are being used to revive you, as you intended),

(b) human lives, even very different humans from long ago, are respected (otherwise why go to all the trouble of dethawing),

(c) there is advanced neurotechnology sufficient to bring people back, and humanity is still around and has learned to live with it,

and (d) society is rationalist enough not to prohibit cryonics out of fear of zombies or something.

It's not perfect, but it's a good filter.
