But that's boring. Let's pretend Gozilla is real. He's been around for a hundred years, pops up once in a while and wipes out a chunk of a coastal city before swimming back to the deep. Killing Godzilla once and for all would be a clear benefit, save thousands of lives and trillions of dollars of property damage. Governments and militaries and smart people work hard developing death rays and mega bombs and Kaiju-specific viruses and, oh I don't know, really big spears. Perhaps one will succeed.
But, he's been around for a hundred years. A whole industry has grown up around him to mitigate the effects and deal with the fallout. There's rapid-response evacuation blimps and self-erecting submerged delay walls and monster insurance. There are collateralized collateral damage obligations to securitize and spread the cost of compensating property owners for military weapons that miss their target. The financial system does what it does well: taking an existential risk, sticking a price on it, and turning it into profit. And it's not just white collars cashing in: there's entire companies that do nothing but quickly rebuild bridges that he chews up, or recycle building rubble into new skyscrapers. There's a whole smorgasbord of mom-and-pop operations that do things like scraping up and disposing of the gallons of his stinky saliva that clog the streets after a rampage (with a little refining, it proves to be a surprisingly effective self-adhesive sealant for leaking pressure vessels). Others specialize in filling in claw-shaped potholes in asphalt. Yet more insulate small buildings against fire damage. Satellites monitor him; subscription services forecast his movements; one company is developing a promising body armor based on studies of a scute found after an attack in Montevideo.
And then one particularly wild plan actully works. Trapped in a constricting net made of nano-scale monofilament and engineered spider silk, Godzilla dies in the shallows outside Cape Town, South Africa. The world celebrates. The next morning, hungover, everybody defaults on their Godzilla insurance. The value of those securitized policies goes to zero. The CCDOs blow up too: finance's innovation is exceeded only by its myopia. Investors take a beating. It's not 2008, but pretty damn close. The business was actually insanely profitable given that everyone in a coastal city anywhere in the world was at risk. The specialist construction and recycling giants lay off people by the thousand. All the independent niche remediation companies shut up shop. Tens of thousands are out of work.
Same thing, innit.
