No, it isn't. It would just require that Americans actually pay for the wars they think are just, which indeed would mean far fewer wars. Perpetual war would be unaffordable. And it wouldn't be the rainbows and sunshine that people like to pretend it would be.

When we enter a deflationary economic paradigm where goods and services trend towards zero that includes military hardware. People don't really think this through very much. People also fundamentally misunderstand why organisms engage is physical power competition to establish their dominance hierarchies.
What is it that people misunderstand?
Why do organisms engage in competitions in your view?
Thanks
People think they can establish a rule of law without the need for physical power competition to establish a pecking order. It doesn't work. Satoshi understood this and created a protocol that is emerging as the largest physical-power-based dominance hierarchy ever created on the planet.
