Interesting thought experiment. I mean, the best way to be able to properly debate someone whose ideas you disagree with would be to construct their argument yourself. Then, you can efficiently reverse engineer it having fully thought it through.
Yea, that’s basically where I’m coming from. Right now I’m writing up a piece tentatively titled “Steelmanning Ethereum”. I want to lay out the best arguments I can in support of Ethereum even though I’ve concluded the opposite. Also, I’m open to seeing what I find out through the process of writing (i.e. the process of thinking).
