När det gäller vanliga valutor är det "bara" att byta till kryptering som är säker mot kvantdatorer (dvs kvantkryptering). Själva pengarna påverkas inte. För Bitcoin däremot skulle själva pengarna påverkas. Det vore lite som att vem som helst enkelt kunde trycka sina egna sedlar som var 100% perfekta kopior av riktiga, och där t o m serienumren var korrekta (på något sätt).

Upon hearing this, absolutely nobody was enlightened. Primarily because nobody could understand Chinese.

Jag håller helt med om att det generella problemet med att vi inte kan lita på kryptering är ofantligt mycket större, men det är också OT för den här tråden.

Det jag (och andra) menar är i princip att de "självreglerande mekanismerna" du nämner sätts ur spel om ett fåtal aktörer har tillgång till kvantdatorer medan resten inte har det.

Här är en artikel som ekonomiblogg har skrivit om bitcoin:
"… all the data shows that most people are not influenced by rational arguments. They're influenced by social pressure. … That's just the human condition, and we just have to acknowledge it and accept it." - Steven Novella

Men man kan fortfarande öka nyckelstorleken. Läste någonstans att en nyckel på en terabyte fortfarande skulle ta orimligt lång tid även för den snabbaste kvantdatorn att knäcka. Förvisso opraktiskt med en nyckel på en terabyte, men inte helt orimligt.
