Isn’t the real hurdle that the human body is composed of different materials that have different thermal expansion coefficients, meaning any kind of freezing or thawing will lead to cracks at all scales, even down to the molecular one?
Yeah, humans are large and it’s hard to freeze the entire thing at the same time even with very cold storage. The outside of you freezes before the inside and that’s problematic.
Smaller mammals like rodents have been frozen and thawed successfully while still living but they are way smaller.

Can we just make smaller humans? Would creating a homo floriensis just to send them on distant stars be a unethical?
Let’s do it and they can ponder our choices when they arrive long after our death.
Wtf!? Just going to casually drop that in there?
Yeah, some caveats apply but https://en.wikipedia.org/wiki/Cryopreservation?wprov=sfla1
