"A sudden random jolt downward in bitcoin price prompts many people to try to sell it and worsen the situation,"
This sentence makes no sense because the "bitcoin price" is actually the BTC/USD ratio. You can trade in other ways.
My final, roll-on-the-floor-laughing moment was the description of dollar as a measure of utility:
"If the utility measured by a single dollar fluctuated a lot, that would mean that the number in your bank account would suddenly miscount the utility of all the work that filled it"
This happens every single day. Every government and bank in the world devalues your current bank account (aka inflation), so that you have to work harder (ie, increase your utility) to receive the same benefit.
"If you’re not willing to have a fluctuating bank account, BTC does not make transactions easier. It forces you to make more transactions."
That's precisely why government provided currencies are also worthless! All of us are running around like chickens without their head, hoping to get 'more money' just to survive! Currency is enslavement IMHO.
