Why we think of a fluid as a continuum, with no gaps, rather than as a collection of molecules

We know that fluids are made up of atoms and molecules so why do we model them as if they are continuous materials with no gaps? This clip explains why

The properties of a fluid are determined by its molecular nature. As an example, the ideal gas equation of state is derived by considering molecular collisions on a piston head.
