I don't actually agree that carrying a large amount of money is inherently stupid. It's riskier than not carrying cash, but doing something risky is not the same thing as doing something stupid. That said even if it was stupid and it was an obvious mistake. Why mention he made a mistake at all? If not to point out that he shares some of the blame because of that mistake? It might be good advice, but only if it carries an alternative. Pointing out a risk isn't advice, it's a warning. "don't carry large amounts of cash because it might get stolen" vs "electronic transfers between two bank accounts lowers the risk your money will be stolen". But I assume we both agree but that's not really a helpful piece of advice in this case.
