Regardless if Satoshi actually knows the right solution to the scaling problem or not, I'm pretty sure this is the exact thing he doesn't want to happen; that we should listen to Satoshi just because he's the one who started bitcoin in the first place, therefore he's right. He wanted decentralization, and that's for both the technical and theoretical stuff.
To be fair, it would still be decentralized. People would still be free to disagree with him, and Bitcoin would still be open source (unless CSW really is Satoshi lmfao). The only difference would be that there will be a clear, albeit informal figurehead, and that there will be no arguments about which chain is "real". The prospect of a single person having that much clout is terrifying for sure, but it's not without advantages -- consensus would be easier to achieve, for example. It's also not like he could dictate what miners and nodes should do, so he won't be in complete control of the network.
I like where we are now, but it probably wouldn't be too bad if Satoshi stayed either. I personally would like to hear his thoughts, divisive as they may be.
