The suggestion is that some kind of tool -- as yet, I believe unwritten -- could generate a list of all members of a category and its subcategories. I imagine this would suit your purpose.
Unfortunately, it would not. At least, not completely. Categorization is not transitive: if article A is a member of category C, and C is a subcat of D, A need not be a member of D. For example: [[Seine]] is in [[Category:Paris]], which is in [[Category:Cities in France]], which is in [[Category:France]], which is in [[Category:Republics]], which ultimately is a subcat of [[Category:Thought]].
But the Seine is not a thought, a republic, or a city in France.
I agree that this often happens, but in my opinion some of these sorts of things are bad uses of the category system and can be avoided (which I do in my own categorization). In particular, categories that are very clearly collections of things, like [[Category:Cities in France]], should *not* contain "related-to" subcategories. The article [[Paris]] should be in [[Category:Cities in France]], but [[Category:Paris]] should not be.
