Bitcoin is the free market alternative to banks and government money. How can we do a free market alternative to insurance companies? Insurance is the natural enemy of public harms like the junk food industry. It could even proactively protect our personal safety and health. The problem is, just like banks, current insurance companies are behemoths that are entwined in the system and lobby the government to stifle competition and innovation. We need free market insurance that is independent of government institutions, just like Bitcoin.
