Right. There's no such thing as "solid", it's just point particles and fields all the way down.

Moriarty, the "boundary" of a solid is the point in space where quantum degeneracy pressure is in balance with van der Waals forces – so there is a well-defined boundary!) Also, I think that "point particles" are a rather illusory concept. More like, interactions between particles are highly localized when observed by a macroscopic classical observer.
