I think these limitations are better viewed as "engineering constraints". They can be described by physical equations, but they are manufacturing or economic limitations rather than those postulated by physics (which tend to occur at the quantum and individual photon level rather than at the manufacturing level). The fact that lenses work, and deliver photons to film, which captures them, means that the photon density and detector spacing is not a current physical limitation. Translating that detector storage to electrical signals is an engineering or manufacturing problem that can be (and has been) approached and solved in many ways. So far the economic solutions are kind of big. But you are right that manufacturing and economic constraints are real, and certainly important if we are interested in commercial products.
