Someone needs to donate blood. Someone needs to donate mosquito nets. But there are already enough people donating blood. We still need more mosquito nets.
Just because you have a comparative advantage in donating blood doesn’t mean it’s worth it. It just means that it’s not a bad idea by as many orders of magnitude.
It costs $130 to $150 for a pint of blood. You have about ten pints, so even if you needed to replace all of your blood, that would still only be $1,400 or so. If it was life-or-death, people would be willing to pay far more than that.
