Except it won't - for the same reason why Nobel donating the prizes for the other subjects doesn't rule out opponents of dynamite or high-explosives for the Peace prize. (I.e. the Royal Academy in Sweden gives out both prizes, the Nobel family and the Rijksbank are not involved.)
Huh? Wasn’t Nobel opposed to (many uses of) high explosives? Wasn’t that the point?
Milton Friedman won a Nobel prize. He didn't like central banks at all.
