There's not necessarily a "who is more worthy of living" judgment here. Future generations are free to turn off the cooling mechanisms which suspend the bodies or heads of the dying, if they deem it important to have the resources now. In the meantime, it doesn't take that many resources to suspend a head; and the burden would become less if suspension became common enough practice that the "extremely expensive, will either fail or make the rest of your life a hell" procedures were phased out and those resources freed up. The problem I have with your sentences is that they prove too much. They can easily be read, for instance, as advocating that it might be worth abandoning medical science.
