For sure I hope the US can get over its addiction to guns. I think thiis would happen naturally if/when Kardashev money becomes officially acknowledged, and issued (again) by the US, because it would defuse the need for all Americans to compete with one another for scarce resources, before that becomes a life or death struggle due to ever scarcifying energy underlying all things. (The energy scarcity underlying all things would be removed by issue of Kardashev money).
Further, it would remove the need for people to be invested in the manufacture of guns, since they would have financial security without need to invest.
Also the government would no longer have any need to switch tax dependence from the harmful fossil fuels industry, to the harmful guns industry, because the government itself would have financial security from Kardashev money.
They could just stop collecting tax, it seems to me.
