Why did we need the military industrial complex in the past? 

Why did we need guns, tanks, aircraft carriers, drones, and nukes? 

Answer: to protect our gold reserves. But after WTF happened in 1971, gold reserves were rendered extraneous and we needed to secure a more productive commodity instead: oil. 

But since now everyone in the world has access to digital gold that can protect itself, the military industrial complex is functionally obsolete. The era of the petrodollar is over. 

The global arms race is now democratized and decentralized. Anyone anywhere can now directly and autonomously protect their time, money, and energy with softpower. 

Bitcoin has not only destroyed every last incentive for war by upending the logic of violence, it has fundamentally rewritten just war theory itself.
