If it was just coffee sure, but where did he get the money to buy rental properties in his early thirties? It wasn't because of rich parents or a machiavellian

If it was just coffee sure, but where did he get the money to buy rental properties in his early thirties? It wasn't because of rich parents or a machiavellian scheme, it was because of a deep anti-consumerist philosophy that extends to everything from not owning a smart phone to riding a bike to buy groceries. Reducing his philosophy to one tiny thing like coffee is like saying a world class pianist could have shortened their practice by 10 seconds a day and still be world class—it's true in the most narrowly-defined strawman sense, but they got where they are by practicing as much as they could, not by looking for corners to cut.
