No conflict. Reality is complex but one should not build more complexity
into ones theory than is necessary.
The principle is that 'entities should not be multiplied without due

What is the due cause for assuming that both price and value vary in
response
to demand?
In a marshallian frame work with a rising supply curve one might be
able to justify it. Is this what you are arguing?

I tend to favour the australian materialist school of Smout, Price etc.

Yes, Lenin did this in Materialism and Empiro Criticism.
