>So, my assertion a little longer spelled out it that I don't think we want giant caches of wealth in small numbers of places. I would prefer active use, I think. But diverse use by many actors is a good means to that. So, if it gets 250k in 100+ banks, that has better odds that someone finds a use that isn't just "credit cards."

Great! This is the first time you've actually said anything that connected "rich people making the world a better place" with "stashing money in multiple banks rather than one". It's still a dubious argument, because in both cases the money would be getting invested, as opposed to gathering dust, and the bank would just invest any excess money it had with other banks, creating the same investment.

It's also really frustrating to have to keep reminding you of what your argument was, in order to get to that point. It would have been much more productive if you had said from the outset "okay, whether rich people's money gets invested at all is a dubious benefit to the insurance cap. But there might still be other benefits, like reduced systemic risk...".

But you didn't do that: instead you acted shocked that I was asserting there were no benefits at all to spreading money across multiple banks, and spoke as if you didn't remember the original benefit you were asserting.

>That said, I confess I also see little value conversing with you

Correct: people that force you to be rigorous in your comments, and don't let you change the topic to hide previous dubious arguments, are going make you look bad. I understand not wanting to get called out on these unproductive tactics, especially if you prefer looking smart rather than learning something.
