This is kind of a brilliant idea.
I don't think this would work. Consider the death cultism of doomsayers for arbitrary future dates. (e.g. radical ecologists) Consider how people act not regarding to cryogenics but to rather simple and excepted ways of increasing life span. Not smoking, limited drinking. Safety issues. The own death is just not NEAR enough to factor in to decision making. There are fun shows set in the near future that are nice and decent. But that does not really change the notion of having ones own time set in some kind of fortunistic way. The reality that the chances for dying are modifiable is not that easily accepted.
I have young and bright people tell me how dying is not an issue for them, since they will just be dead and feel nothing about it. Its a big scale UGH humans carry around.
Anyone around here know how to pitch a TV series?
Be a producer or big scale writer on another TV series. Keep in mind that narratives are sold on interesting characters and plot. The background of a society is not of particular importance. The current trend is for darker&edgier, after the shiny world of Star Trek.

Terminal values and preferences are not rational or irrational. They simply are your preferences. I want a pizza. If I get a pizza, that won't make me consent to get shot. I still want a pizza. There are a virtually infinite number of me that DO have a pizza. I still want a pizza. The pizza from a certain point of view won't exist, and neither will I, by the time I get to eat some of it. I still want a pizza, damn it.
Of course, if you think all of that is irrational, then by all means don't order the pizza. More for me."
