The assumption there is that trackability is a desirable characteristic to have in a technical system. As someone who sees technical systems as the onramps to centralized abuse by institutional power, I don't see trackability as a feature, but rather an anti feature.
Consider this: just like fraud, the ideal amount of it in any purportedly liberal civilization is non-zero, because the freedom from which is derived the opportunity to engage in the behavior is more important than perfect attribution, detectability, and prosecubility of it.
People don't realize that when you set goals of zero'ing out these sorts of things, you're throwing the baby out with the bathwater.
