I really doubt Satoshi ever saw bitcoin becoming this big, he created something with the mindset of a person of academics and he was just focusing on making something that he thought would be a lot better alternative to fiat money but in the end he wasn't expecting millions of people trading billions of dollars everyday on a trillion dollar market. That is not something you would even dream about when you are making stuff up, like when I dream about having a big house of my own I am dreaming about stuff like american suborbian tv show houses not a huge castle in UK, that would be too unrealistic.

Well, same thing happened to Satoshi, he would have expected the close circle of him that is interested in this would definitely look into it but he wouldn't even dream of something this big.
