For example, that blockchains are based on assumptions about the distribution of processing power. And when you use it outside the context of bitcoins, you still need an incentive for many people to contribute, ...

I would just like to know on what basis they can say it is PQC without any NP problem reduction. I believe that the point you're making is assuming that a Quantum Computer could solve any problem in NP that's not actually NP-complete quickly (or, at least, in polynomial time). That's not known to be true; Quantum Computers would be able to solve some ...

Let's approach the question from this direction. PAKE tries to solve this problem: Alice has a password $PW_{a}$, and Bob has a password $PW_{b}$; consider a protocol where Alice and Bob exchange messages, and generate encryption keys $E_{a}, E_{b}$ where $E_{a} = E_{b}$ if $PW_a = PW_b$ (and unrelated if $PW_a \ne PW_b$); if they're the same, Alice and Bob ...
