How they differ, and why it matters
I think there are more exceptions to this in Web3 than just Nakamoto. What about the DarkFi/Lunar Punk narrative epitomized by Amir Taaki (if unfamiliar, you can check out the interviews on Epicenter)? Although there is a lot of pragmatism in the face of the panopticon in Lunar Punk, it is also a visionary anarchist worldview. Maybe Taaki isn't a fan of heros, but I would definitely identify the Lunar Punk vision as epic. Maybe another way of framing this; if Web3 can't be revolutionary, why bother? I don't think lore alone has driven the Web3 movement.
I'm curious: when are you going to use the word "vernacular." With the definition you've provided here, I can't help but think of it. For example, I'm reading a number of books right now in a genre called "vernacular architecture." One example of vernacular architecture: great camps of the Adirondacks, constructed out of spruce logs harvested on-site. There's a lot of lore here. I'm also thinking about Dark Mountain Issue 8: "Techne," which is really about craft in the deep sense of the word. Lore (and vernacular) are where the pragmatic and the beautiful meet.
