Most of the people I know who think like this don't actually have kids and many probably never will.
Allow me to be your sample size of one, @Laeserin. I think like this. I am a parent. But taking your point as a potential indicator of a significant archetype hodler, and thinking optimistically, maybe future bequests to non-family beneficiaries will be championed by childless hodlers. Can you imagine prominent buildings in future civilizations like "Laeserin Free Library" or "Laeserin Center for Nutritional Research" for instance?
