he'd expect gourmet cooking

Isn’t that the same fanonical trope, essentially? :-) After all, I don’t think he ever shows a single “canon” inclination for luxury living during the entire series - unless ice-cream is a black-market luxury goods in the future, of course... Buying himself safety, or the notion of being “untouchable”, are the only official reasons he gives for his desire for money, as far as I’m aware.
