Somewhat surprised at all the revulsion to this post. I live pretty similarly to this fellow, but it isn't the least bit boring.
When I finally saw the right bicycle, I spent about $450 on it, then rode 100 miles on it. It was a life-changing adventure.
When I finally saw the right sailboat, I spent about $2700 on it (less than many/most HN'ers paychecks), then sailed 100 miles on it with the wife. It was a life-changing adventure.
It isn't up to me to say which way of living is best. But I'd lay odds that I'm going to be pretty well satisfied with the one I've chosen, when my last day comes.
Incidentally, Alex doesn't appear to be 'hoarding' cash, he just seems to have saved up a couple months' glide path, something everyone is supposed to do, but according to the recent CNN article, almost nobody does. When interest rates go back up, this seems likely to change.
