More importantly: does it really matter what Satoshi thinks? Us hearing Satoshi's opinion on things would only do more harm than good. Surely one of the reasons why Satoshi preferred to stay hidden is to prevent bias when the community is debating on things(scaling solutions, etc).
I have a different opinion when it comes to scaling, if Satoshi was around i am sure he might come up with a good solution that would be acceptable to everyone, if he can invent something that looked like impossible before bitcoin, i am sure he might have some idea about the scaling issue we had to encounter too, because he never created bitcoin for a selected group of people, he invented for the entire world to use.
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.
