Perhaps I'm misunderstanding what you mean when you say, "I disagree on every level except the binary 'someone is trustworthy or they aren't' level." What is it specifically that you disagree with?
You said
There is nothing anyone can do to prove they are trustworthy. Someone can only be proven to be untrustworthy, and that's only after they've scammed someone, not before.
This seems to imply that there's no such thing as partial trust. There are things that anyone can do to partially gain my trust.
I see. That's not what I meant. I meant there is no way for someone to prove they are
100% completely trustworthy and eliminate every possibility that you will get scammed.
Huh? There's nothing to interpret. You're reading way too much into my statement. There is no hidden message to decipher.
Why exactly don't you want to make a bet? With a bet, you tie up no capital and have a positive EV.
Because I can invest whatever amount I'm willing to risk with JD on the side of the house, which also has a positive EV. I believe JD is a lot less likely to turn out to be a scam than you do. But, if I'm wrong, I only lose what I was willing to risk.
