Edit: Ok, now I see what you mean. I do not agree with you, although it is a matter of opinion. My opinion is that there are more important social priorities than making rich old geezers live longer and that your plan depends on numbers that could go one way or the other. You could easily build a scenario where your plan decreases hospital blood availability, and this seems likely to me given the financial incentive.
If on the other hand, that is just an excuse because you're morally opposed to old rich people living longer... ?
Right now, we don't have enough just for the people in the ER. Not saying it can't work, but it seems to me that the potential for catastrophic failure on a social level is quite high.
Your thinking on this is a bit short-sighted. Right now, this might only be available to “rich” old geezers. With test-tube burgers already under development, it seems likely that test-tube blood isn’t much further off. By the time you are an old geezer, blood will be a cheap commodity. But only if we get started on the problem now, instead of shooing people away with moral scare-mongering.
So I prefer to rely on verifiable present-day fact to decide on socially critical issues.
Relying on a partially captured government to set the right price is dangerous in this case.
