Many musicians, even famous and successful ones, do just that.
I love food, including expensive, fancy food. I grow vegetables, and I have a CSA where I get local vegetables weekly.
Food like Myhrvold's, to me, is rich, ignorant assholes behaving like rich, ignorant assholes. I say ignorant because while they may be well versed in certain areas, their knowledge is very narrow and skewed. They fancy themselves adventurous intellectuals, when in reality they are precisely the opposite. They are some of the most closed minded people you will find.
Also, for anyone who doesn't already know, Intellectual Ventures (Myhrvold's IP troll firm) is one of the worst. A little Googling on their actions tells you everything you need to know about what kind of person he is.
