I'd pack my bags at this point too if I were you.
Let me leave this for anyone who comes across this thread, hoping for a neat conclusion.
You have posted a Lindblad argument that assumes the noise scales quadratically. That quadratic scaling is the basis of your N<170qubits.
Atom and microsoft have demonstrated logical qubits operating at an error rate four times better than the physical error rate. Other global teams have demonstratd similar. These results are empirical proof that the noise in their systems is correctable, and therefore does not scale quadratically, and therefore the actual noise profile is not following the eventually catastrophic scale path that defines your math (that ends up bing-bong at170)
It's one or the other: Either atom and microsoft and quantinium and harvard and everyone else are lying and it’s all a scam—or your argument has already been proved wrong by experiment.
Both these things cannot be true at once, that is impossible.
Passing reader: which one do you think is true? .
