You don't know that bitcoin's settlement capabilities will shore up the quality of our fiats
Is this a joke? None of the crap you say makes any sense then you post this horrific shilling for the central banks statement LOL. The further you abstract money from barter the bigger a scam it is. Using a physical, commodity based currency (noble metals in native coin format - you know, like gold coins, silver coins, copper coins, etc) is about as close as it gets to barter, which is why it's generally the only non-scam monetary system.
I don't want to hear any of your Keynesian garbage where you attempt to obfuscate the monetary system through a Rube Goldberg machine in order to scam people whether it's bitcoin or some other poorly constructed Rube Goldberg likes the ones CBs already use. Occam's Razor wins in the end and shekling scammers can BTFO.
