The whole point of quantum error correction is that it preserves entanglement. (QEC in practice is not a panacea, for instance, transmons can escape in higher harmonics which are not corrected for.) For the claim, "fundamentally unscalable" however you should bring some evidence. Best, Bas PS, for those that want to get into the topic, I recommend Nielsen & Chuang.
