This type of thing is easy to joke about, and I definitely bought my share of thousand dollar cookies.

But I think it's important to remember that by buying those sandwiches and pizzas - and buying them with BTC, not by converting to cash first - early adopters paved the way psychologically for people to believe that BTC are actually worth something. Who knows whether the bitcoins that bought those things would really be worth that much now if they hadn't been spent?
