Ever since it was discovered that people could send information encased in arranged groups of electrons, a realization about the nature of that information began to set in: It was no longer as secure as it had been before.
Physical objects were easy to keep track of and catalog. They were harder to replicate, which made it easier to control their numbers. Large numbers were correspondingly harder to move, or lose, than smaller numbers. And they could be locked in a coherent space, with no chance of somehow seeping through the cracks and escaping. But the new digital file presented a problem that was as far beyond the constraints of physical objects, as a horse would be compared to a slug. And whereas you can confine a group of slugs with the simple expedient of encircling them with salt, you need a considerably more sophisticated method to corral a herd of horses.
