If there were no loopholes to Bell's theorem I would agree.

> Weak measurements do destroy some entanglement, just not "all" of it.

IDK if that's true. Are all methods of observing probabilistic states destructive forms of measurement?

Does a camera on a candle diminish the candle, or does it take energy (and information) from the "wake" of the field moments or field disturbances?

I don't think that anyone realizes that it's possible to infer photonic phase from intensity (by Huygens-Steiner).

Which measure of degree of entanglement best characterizes state linkage across spacetime?

Depending on definition, doesn't a laser pointer entangle phase states across spacetime, but only slower than c (the speed of transverse photonic waves in a total vacuum)? Are the states synchronized with a constant delay?

Quantum discord: https://en.wikipedia.org/wiki/Quantum_discord :

> In quantum information theory, quantum discord is a measure of nonclassical correlations between two subsystems of a quantum system. It includes correlations that are due to quantum physical effects but do not necessarily involve quantum entanglement.
