Did you read his comment? His point was that the OP seems to think we can't indulge ourselves occasionally and must always work towards solving those big problems. We're human. We should allow ourselves to have some fun once in a while.
That's not the context of the quote. He's wondering if people will bid over the face value of the card, or if no one thinks that charity is more important than caffeine. He's not dissing on Jonathan's Card, he's wondering about his auction.
If people don't bid it up, I'd say the appropriate conclusion to reach is not that people don't think charity is more important that coffee, but that people don't trust a thief.
