If Q lacks a value in the P-measurement situation, the interpretation is no longer a hidden variables interpretation of the relevant type, and blocking the Kochen-Specker argument becomes unnecessary.
A specific scenario or context in which a physicist is measuring a particular property (represented by 'P') of a quantum particle.
Value (in measurement context)(quantum mechanics philosophy)
A definite numerical result or property that something has—in quantum physics, whether a particle has a specific measurable outcome before or at the moment of measurement.
(a) We might think that v(f(Q)) just is not a self-sustained physical property, but one which ontologically depends on the presence of another property v(Q). (Recall that in the proof of FUNC v(f(Q)) is constructed from v(Q).) But, since the position does not reject questions about values of f(Q) in a P-measurement situation as illegitimate (because it does not trade on a notion of an observable being well-defined in one context only!), this seems to lead to new and pressing questions, to say t
