that's actualy a very nice proposal, but Bitcoiners love their Bitcoin, it's not a racional decision. Community would never give the "Bitcoin" up
But we don't need to give up BTC. I don't want to give up bitcoin either.
What I want to give up is "mBTC" and "µBTC".
You sugested to use Satoshis, so there would be no "Bitcoin" anymore
EdIt: Bitcoin would be a multiplier like saying "a million (dollars)"
