Well, I would say it absolutely is possible, but it costs money directly, up front and in an accountable manner. Security incidents vanish in the fog of responsibility diffusion and nobody specifically can be blamed. That means for each individual responsible party, it is the rational choice to do just enough not to be blamed, pull off theater to seem engaged, but avoid anything that would actually cost money.

So, you’re kind of right, but for the wrong reasons. It’s a systemic issue, that almost inevitably happens in large organizations, but at the root is not inherent complexity, but a perverse incentive structure.
