It's amazing that's what makes him realize the issue.
Granted there aren't necessarily enough details on his income / assets / debts / lifestyle, but he's a best selling author.
This raises an interesting question that was spoke of in the 'Rich Kids of Instagram' thread a little as well.
If he spends $1MM/yr in his lifestyle, and say ~500k/year on super high end designer clothes. One would definitely say that a disproportionate amount of his spending is on his addiction, and it's incredibly wasteful.
However, if he's a best selling author with a net worth of say... $25MM, he essentially follows the 4% rule!
I guess the difficult question is, in an ideal world he'd be donating to charity instead of buying up hyper-expensive ostrich skin (!) jackets, but provided he's not putting his family or financial future in danger, who are we to judge?
