The part where I’m talking about targeting is manufacture and development. It’s not realistic to penalize steel and petrol and other materials because that gets too messy and complicated.

Weapons should be manufactured only by one’s government for express use in defense. No one should get paid more than a modest salary (something fair for their labor; I hadn’t given it thought enough to say more than that at this time), no one in charge should make huge salaries or bonuses, it should be a thing people do because it pays rather than because of enrichment. Like how no one gets massively wealthy delivering mail or hauling garbage; sure, you can do quite well in some instances, but you’re doing it to put food on the table rather than to gain power.

Sorry that I haven’t more developed thoughts at this moment. But something roughly resembling this is what I had in mind when I posted the prior comment.
