It's a test. Honestly though, even the trust-bustiest of onlookers probably wouldn't call everything Buffet considers "moat" a monopoly. I buy fairy dishwashing soap. If the supermarket doesn't have it, I like the supermarket slightly less. If it's 10% more expensive, I still buy it. Home brand dishwashing liquid doesn't have this advantage. That's a moat. It's not really a monopoly though, just a "relationship" with customers.
