> So what makes some business models (selling physical stuff) more protectable?
Food is a scarce[1] resource. Concepts like "property" and "theft" relate specifically to managing scarcity. Taking food deprives the owner of their meal, because we cannot make perfect copies of baryonic matter. After Shannon introduced the idea of "digital communication" that allowed information to be copied indefinitely without errors, the bit was no longer scarce.
Note: I didn't say anything about how the information was created in the first place. The creation of data - which requires work/energy - should not be conflated with copying existing data. The method used by the restaurant to create or acquire a recipe doesn't create the scarcity that is inherent to the food that implements that recipe.
