I sadly somewhat agree. I had a discussion ~ 1.5 yrs ago on here with someone where we both had the same thought: what saves bitcoin users from slightly weak nonces being dangerous to their funds is non-address reuse. (I recommend the paper "biased nonce-sense" by Tanja Lange et al on this). If you use nostr keys as bitcoin keys then even 1 or 2 bits of bias in your nonce generation could be enough to lose the funds.
