Why does there have to be one specific combination of these aspects that yields the one, true "intelligence"? The truth is that it is simply an extremely extremely broad spectrum. Any agent that performs useful computations can be argued to be intelligent in some way. It does not make sense to argue endlessly in an attempt to lift this lower bound. Let's just acknowledge that slime molds, bacteria and NPCs have some form of intelligence so we can move on and define more specific and useful types of intelligences: Embodied intelligence, social intelligence, learning intelligence, general intelligence etc. Of course these will always be vague spectra, as nailing anything clearly down is extremely technical. Organizing things in sets is nice and all, but it is usually ill-defined on the boundaries and when it leads to endless discussions it's better to just think in terms of functionals. Some abstract functional tells you how intelligent, how embodied or how learning a certain agent is, according to some scale.
