this is not convincing at all. we pretend that we can have perfectly isolated quantum systems (a particle, a few particles) and we can reason about and extrapolate the findings. we cannot have isolated particles - they can be regarded as isolated for experimental purposes but the reality is that probably the whole universe is a massive wave function that encompasses everything and we can approximate in some really special cases (ie system above). we also pretend that consciousness is something special and altering the state a somewhat complicated wetware had consequences on “reality”. it doesn’t. the measurement problem is an extremely good example of how we think. a measurement does not make sense to a cow. it’s abstract. we made it up. we have conventions that help make it useful, but those conventions break down when our senses (or things we use to amplify out senses) cannot measure what we want to measure.
