Quantum field equations capture entanglement. Measurement choice impacts the field equations, because you are field equations too. So none of those problems exist. Just interpret the field equations as they stand. Yes, new information is information is conserved, if everything is predictable. Which the field equations are. That would not be true if collapse was real, as that would impact the system with new, previously unknown, inherently unpredictable information. (The fact that we as big things end up experiencing what looks like a collapse is explained by the field equations and the statistics of how quickly information, not carefully controlled, gets dispersed. At this point in the history of physics, we should be able to discard extra explanations for our experiences that are already completely and exhaustively explained by the well tested laws. The fact that the explanation requires thinking about things differently than ordinary experience, isn’t an excuse for wedging poorly characterized and completely unnecessary fudge effects as shims into our intuition gaps. I am, of course, not arguing that collapse isn’t a useful concept, with many pervasive practical uses when full systems are not being modeled.

> Measurement choice impacts the field equations, because you are field equations too. This sounds nice, but doesn't actually work if you try to apply it in practice, because however many experiments you'll perform on classical objects, you'll only ever observe properties for one basis of measurement, whereas you'll get different results for different bases for quantum objects. In other words, how come when I observe a single atom, I can see it in a state like (1/sqrt(2))|spin up> + (1/sqrt(2))|spin down>, but I can never observe a basket ball in a similar state? If it were just a matter of my field equations happening to only match certain kinds of states, that should apply exactly as much to a single atom as it would to ~6,022*10^23 atoms.
