I've got a doctorate and I don't really see what you are saying, primarily because "no objective physical reality" is somewhat vague.

QM, for example, is a totally adequate theory of objective reality! it just describes an objective reality with properties which differ to some degree from those intuitive to creatures at classical scales. It may be inadequate in other respects (not invariant, a little unsatisfying wrt the born rule, etc) but it isn't as if it implies NO OBJECTIVE REALITY.
