Hahaha. I can function quite well without a car but that’s beside the point.
The ultimate conclusion of your line of questioning would be “if you were in a life or death situation that could only be solved with Fiat, would you sell your Bitcoin for fiat then?”
Even if it were possible to create those conditions (which it really isn’t anymore - I can buy most anything I need with Bitcoin now), the answer is still no. I am a admittedly a zealot who believes I am at war. And yes, I am willing to die for my beliefs. After all, people have gone to war and died for millennia now and for much much stupider reasons that never stood to benefit them directly at all.
I have no debt though, live a very happy life many multiples below my income means, am approximately 90% self-sufficient anyhow, and have no children to worry about.
With a weapon of peaceful protest like #bitcoin, I like my odds against my enemy.
