But it didn't happen in a vacuum. Cheap shipping certainly wouldn't be possible without containerization and improvements in logistics, but the new system only made sense when scaled up to giant ships (fuel and crew size efficiency), which in turn only became feasable when ships could quickly/easily onload and offload at multiple ports in multiple countries, without quarantine/ security/ customs delays at each port.

You could say it's a chicken & egg situation, but the scale of the containerization age only began to make sense in the context of relaxed regulation and efficient import/export policy.

Also, it wasn't a case of non-existant regulation racing to catch up with a booming new technology (ala the internet or Uber/Lyft). International trade regulation has been around since before, well, nations were even a thing. It's the original bureaucracy. The regulation had to be addressed first, or at least simultaneously. Which to me is as impressive, if not moreso- cutting through a worldwide rats nest of bureaucratic red tape in so little time. (Regardless of if you agree with the resulting policy.)
