  The third (related) objection is that no matter how dangerous paid donation is, it need not be any more dangerous than unpaid donation, since the mere fact of payment does not add any danger. So if paid donation is wrong because of the danger to which the donor is subjected, then free donation must also be wrong on the very same ground. Free donation, though, is not wrong; on the contrary, it is generally regarded as commendable and heroic. Therefore, paid donation is not wrong either; or, if it is wrong, it is wrong because of something other than the danger to which the donor is subjected (Radcliffe Richards 2012; Wilkinson and Garrard 1996).
