I can't overemphasize the risk this misuse of blood products represents to healthcare systems around the world. This is an anti-vax movement waiting to happen: "Billionaires looking for a fountain of youth get blood transfusions from young bucks? WTF?" blends easily into "Why should I donate blood if they're just going to sell it to billionaires?" This would be catastrophic for trauma resuscitation, surgeries of all kinds, and a variety of medical patients.
There should be severe penalties for soliciting service like this. Imagine if solid organ transplants were handled in the same way: "Young man, as a new intern, I'll give you a percentage of my Facebook stock in exchange for a kidney..."
The next problem: it will only take one high-profile transfusion reaction to crater the public trust. If the biology nerds in the audience want to distract you with fancy talk about the low risk of certain molecular things happening because "it's just plasma", skip it. Simple, mechanical transfusion-associated circulatory overload is plenty enough to kill an old guy with stiff arteries and hypertension.
And the worst part is the lack of science being used to drive a supply chain decision that's highly science-dependent. This is so ethically corrupt I don't even know where to begin. The FDA's statement pales in comparison to what I'm sure the inspectors are actually feeling right now.
Please, if you know someone soliciting this kind of transfusion (recipient or physician), encourage them to read the FDA statement.
