It’s really important that you understand what’s really involved in getting a nuke. They aren’t sitting on shelves in Walmart under a sign that says, “$30 Million! Always Low Prices!”
The unit cost includes billions in fixed overhead setting up factories, assembly lines, etc. It’s only that low because they’re made in large quantities. But without the DoD, there is no nuclear weapons industry, no wholesale market, and hence no suppliers for Walmart’s “Nuke” section. Our hypothetical madman has to build the factories, tool up the assembly lines, hire the workers, build silos and bunkers, pay for maintenance, and staff his silo with people willing to push the big red button–but whom he can trust not to launch it without his orders, or blackmail him, or target San Francisco just for kicks.
Some of those costs you’re ignoring because you’re overlooking that the US buys nukes in bulk, and that’s something the world’s richest men can’t afford. And other costs you’re ignoring because they’re sunk costs: manpower is a non-issue when you have an armed force that employs millions; trust is not an issue when you can use triply-redundant systems and can court-martial the disobedient and have them shot; testing grounds and silos aren’t an issue when you own billions of dollars worth of property; maintenance is not an issue when you have the aforementioned slave labor and a bottomless budget and access to printing presses; etc.
Another problem is the casual assumptions you’re making about this guy. Our hypothetical madman is rich enough to afford nukes, which means he has considerable capitol. But he’s crazy enough to want to kill millions of people. He made billions in business by convincing people to give him money, but wants simultaneously to lose those billions with no hope of recouping the loss while killing people en masse. So he’s smart and sane while at the same time being incredibly insane and/or suicidal.
Note that you aren’t describing Bin Ladin! First, he’s only worth 300 million–less today, since that was his worth before his assets were seized after 9/11. That might be enough to get a bomb or two, but it isn’t enough to spin up production on an arsenal, let alone pay for silos, etc. So he isn’t rich enough. He also isn’t crazy enough: he attacked the US in retaliation for its past interventions in the Middle East, and present military bases on the Saudi peninsula. Without such provocation, he wouldn’t have perpetrated 9/11, and would undoubtedly have found much more effective ways to spend $300 million advancing Islam than in building one or two bombs which would horrify the world’s one billion muslims to such a degree that any spiritual influence on his brethren would be nullified. You aren’t describing Bin Ladin–you’re describing a comic-book supervillain.
And finally, you’re ignoring the fact, repeated several times now, that people don’t want to be nuked. Free-market, civilian anti-proliferation organizations are guaranteed to exist–and unlike government, they won’t build nukes in order to oppose nukes. They’ll make contractual arrangements with uranium exporters to facilitate “open-source” public monitoring of large purchases. They’ll villify the hell out of Warren Buffett as soon as he starts building his enrichment plant, which will result in boycotts and divestment leaving him flat broke–because remember, Buffett can’t print more money, or arrest people for revealing his “state secrets,” or command legions of cops to tase people. He’ll be ruined, his neighbors will stop speaking to him, security agencies and insurers will drop him. And that’s only the legitimate response; Buffett would then have every reason to fear unstable or terrified persons assassinating him–which, recall, he has no army to prevent. Privatized non-proliferation is not only possible; it’s relatively uncomplicated.
Finally finally, remember your hypothetical supervillain? Would you rather he manages to pull together a conspiracy to build a handful of nukes from scratch, or would you rather see him become president of the United States? After all, you’ve hypothesized that he’s fabulously wealthy, successful in business, and completely insane. He can surely get himself the presidency. If George W can do it, any filthy-rich psycho with a folksy manner can do it.
