> Another way to say it may be that it's impossible to separate observation from the intrinsic properties of the world.
I think it is more parsimonious to say that there are no intrinsic properties of the world that are not relational, not that they are impossible to separate from observation. It defeats the purpose of interpretations like relational quantum mechanics to hold on to the concept of an intrinsic reality when the interpretation makes such a concept superfluous.
I would say that it is impossible to disentangle the intrinsic properties of the world from observations in the same way that going north of the North Pole is impossible.
