You are arguing that printing money and giving it to certain contractors is bad for other people which is just obvious. These contractors are still going to spend the money they got which means more money in the system and thus money buying less commodities.

Yes inflation isn't a force of nature, it only exists because of how the dominant world economic works, that doesn't mean that the inflation is arbitrary or made up, there are things that obviously cause inflation and studying what those things are is meaningful for as long as the dominant economic system stays the same.

I would also love to hear what you're suggestions are for how things should work, saying the current system is bad is completely worthless as long as you don't have an idea for what would be a better system.
