Not sure why you're arguing this point, when numerous people have shown the ability to lose large fortunes quite easily. Just because you have no desire to blow money at the rate that others do is not evidence that it can't be done.
As an aside, you do realize that many of the most successful sports teams on the field are also some of the biggest money losers, right? Sure, they bring in a lot of revenue, but it gets spent, and then some.
What I'm saying is it is hard to spend money being reasonable. Anyone can just buy 10s or 100s of something and not use it. Or donate it all. That's not what I'm debating here.
There's only so many cars you can buy and drive and want to maintain. After a certain point, you are just collecting and never using. There's only so many homes you can buy before you just don't even show up for over a year.
Get what I'm saying now? It's very hard to spend money after a certain point.
