I don’t think this motivational power is actually replaceable by a more generic abstract preference. (Or else charity fundraising would just say “we offer 20 utilitons per dollar” and that would be enough.)
This does not follow. If the motivational power of sadness is replaceable by a more generic abstract preference, but most people do not perform that replacement, then charity fundraising would appeal to the “most people” baseline.
