There are only a handful of people on the planet that could reasonably claim that $1.4 billion doesn't matter that much to them (and none of them are likely to actually hold that belief).
It's an absurd premise to claim that 80%-90% of someone's wealth does not matter much to them. Not to mention implying all sorts of horrible things about their character in the process (to claim what you are, is identical to claiming that Spiegel is ok with losing that money as opposed to keeping it and doing something good with it, that he would feel indifferent to the contrast of said scenario).
I believe the point is more about the marginal utility of wealth and what additional products and services $1.4 billion can buy relative to the $250+MM net worth they have now.
It's possible that aircraft carriers aren't purchased and constructed with cost as a factor. Or if it is, a higher cost may be considered a positive. ;-)
