Note that. The primary mechanism in error-correction paper is "selective quantum observations". It means we don't need to use all available resource but selectively error-correct. Similar idea is also recently explored in quantum chaos, whereby system is still chaotic but localisation can be observed in the ancillary system.

Related phenomenon is quantum Zeno Effect, https://en.wikipedia.org/wiki/Quantum_Zeno_effect Zeno Effect appears over selective observation, rather than selective states.
