"Nuclear weapons don't kill people. People kill people". So obviously we should let everyone order their own personal nuke from Amazon and let the market sort it out, or something.

Technology concentrates power. Yes, people may be the problem, but "taming technology" is obviously not a "flawed premise". There is a big difference between people having the power to bludgeon their neighbors with sticks and stones compared to blowing up entire continents with nukes.
