2) I think there will be unforeseen consequences down the road for people getting the infusions. Something from a bad Stephen King novel....
“People donate their blood and he makes $8000 selling it. Hmm.....”
It’s likely to be paid-for plasma, not donated. When I was in college, oh so many years ago, and I wanted a couple of bucks for Friday night, I would sell my plasma. They would take my blood, centrifuge it, transfuse the blood cells back in and keep the plasma, all for $15 a pop. You could sell plasma every couple of weeks.
However, given the changes in lifestyles over the years, I wouldn’t want any plasma from today’s likely sellers.
