I wonder if one of the things I would occasionally have to do if I was really, really, really rich would be to avoid spending some small percent of the money on researchers, fact-checkers, the occasional private investigator, and a PR person in order to "win" arguments on the internet - whether by lining up the evidence about the facts in question or about the hypocrisy of the posters - without getting permabanned from whatever the site was.
For that, and similarly silly reasons, I think I would need to force myself to give all the exorbitant parts of my wealth to good charities and causes so that I didn't have the leftover to waste.
