Who's talking about ridiculousness? We're talking about the lack of hoarding, so if he is spending ridiculously instead of hoarding, then he's still not hoarding, which is the point.
You think it's ridiculous that he's not hoarding, well, sounds like that's something you need to work out in your own head.
I would say that it's a good thing such a ridiculous person just gave up a bunch of his money. Good thing that money is no longer sitting in the bank account of a ridiculous person.
So this is a sign that rich people don't hoard their money. You seem to think that this is a particularly ridiculous rich person, so even better that he's not hoarding his money.
