I don't think death is an appropriate punishment for much of anything, but try telling that to the second law of thermodynamics... or for that matter, the state legislature of Texas.
Fiddling around with preferences given a condition of absolute abundance is good for figuring out direction, but not distance. Scarcity and diminishing returns present different challenges. This is not a question of what, but of how badly, of how much would be good enough.
Would you be willing to become batman for this? Say some obnoxious redneck at a Tea Party rally shoots himself in the foot, gets infected, the faith healer can't fix it so it just gets worse until his whole leg smells like the week after Gettysburg. Would you break into the morgue, cut off his head and have it cryopreserved, at your own expense, against his wishes and the wishes of his surviving family, if you had the cash and were reasonably certain you could get away with it? How much do you care?

To be honest, yes, that does sound like a net moral pos...
For a lot of serious charitable causes, people expend tremendous resources on 'raising awareness' which probably, on net, accomplishes little or nothing for the cause it nominally supports. For cryonics, though, the technology already exists, the target audience can pay for it themselves, the main obstacle is genuine ignorance and perverse fear-of-death countermeasures.
The second problem seems intractable, but in the long term we can just let the blind idiot god fix it.
For the first, have any of the organizations involved considered saving up for, say, a superbowl ad? Or even just some youtube videos. I am imagining it set up as a conversation between two people in, say, an office. The skeptic brings up some plausible-sounding objection (sticking to the saner stuff), which is illustrated by cartoons with the continuing conversation as voiceover.
See, I talked to a relative of mine, who I respect very highly, on easter. She's planning to get cremated. Mentioned some technical objections which I know have been resolved, but which I couldn't adequately explain on the spot, and didn't know where to point her for the source.
