Kinsella on Utilitarianism

In a comment over at The Cobden Centre, Stephan Kinsella wrote:

utilitarianism is methodologically flawed (value is ordinal not cardinal and not interpersonally comparable) and morally bankrupt (it's immoral to steal from A to give to B even if A is richer, even if the money taken "means less" to A than it does to B)

It is a wonderfully succinct condemnation.
