One of the weirder ideas I’ve encountered on the libertarian right is that deposit insurance is evil. Not that it’s unsound or misleading, but that its goals are immoral. There are people who want depositors to be ruined if a bank fails, and that’s just what you get for not personally auditing your bank, sucker. The thought of someone getting money out of a failed bank makes them legit angry. Maybe because they put their own money into surivival gear and won’t get to use it? idk.
I’d say it’s related to the central role risk plays in the moral imaginary – where the ancients might look down on moneylending as immoral “money reproducing itself” without any effort on behalf of the lender, and socialists might say that “labor is the source of all wealth”, the libertarians hold that capitalists (incl. lenders, incl. those lending to banks as “depositors”) are doing something vital to morally deserve profit, and that’s bearing risk. And without that (it’s the same dynamic that recoils at bailouts and “crony capitalism”) you are the undeserving caricature being wrongly rewarded for nothing more than having money already.
