Just my interpretation.
Satoshi didn’t just create Bitcoin using the tools that existed. The vision was very clear. In his brain this tech is designed to ingulf everything, flip the entire system on its head and take its place. And you can read it in all the emails.
This wasn’t like…Uber, saying we have the internet, we have cars, we have mobile phones, let’s connect people together to help each other out. It was more like If Uber designed their app to delete the idea of car ownership, make transportation a service, and people won’t even need to request a ride. Cars will be pulling up in front of people houses based on their schedules. Or some insane ultra futuristic ideal case.
What I’m trying to say, he came with a vengeance. Not necessarily in an evil way. More like in a Batman way.
