I totally agree. All physicalist concepts: space, material, etc. work perfectly fine as a subset of an idealistic universe. You are then just describing those ideas which are consistent and useful enough that they are worth cataloguing and investigating. Whether a concrete bridge is really, really real in a physicalist sense, or is a composite of ideas about gravity, friction, tensile strength etc. doesn't matter anyway.
What does matter is that the existence of mind is a totally wash in any physical explanation without redefining terms to make it mean what it doesn't
