How do you afford the food to make the blood without charging for it? Again, why are blood donors expected to do it out of the goodness of their hearts for no reward, but the companies can make as much money from it as possible, forcing people who are dying to pay for their lives?

We’re also looking at this in a binary fashion which isn’t the only way. Why can’t they just sell the blood at cost or at a low margin to cover their expenses without going into basically extortion of the receiving patient? What’s stopping a competent, democratic government that works for the people from imposing those restrictions on medical companies in the interest of saving lives? Or even nationalising and tax funding blood processing to make it free at the point of access? We’re not going to make blood universally free overnight (that should still be the end goal for humanity as with all essential resources), but when you stand to go bankrupt from a single blood transfusion, it’s a much bigger problem than “merely” charging for blood.
