I’m just surprised there isn’t a shadow industry of selling blood products fed on people altruistically donating for free (like, as far as I can tell, every country with public healthcare does) with corrupt pseudo-legal marketing ensuring that blood products are not sold for profit (because they sell the bag, not the blood, or they sell the service of delivering blood, or some bullshit like that)
That’s only because capitalists are deaf to reason and demonstrable facts.
