how is it absurd when this is what consumers are saying they want for themselves as well. It's revealed preference.

Very much agreed. Perhaps one component is a kind of identity drift. I'm not quite the same person I was a year ago, nor am I quite the same person that I will be a year from now. To say that $1 I get now goes strictly to me, while $1 "I" get a year from now goes 99% to the "me" I am now and 1% to something different seems like a plausible part of the temporal preference.
