Consider: the majority of critical physical infrastructure of modern-day society could be disrupted trivially, and with very little risk of consequences.
There are vast swathes of unguarded infrastructure that could be attacked without anyone being there to spot you, or having any real way to track you down. Nobody would notice until it were too late.
And yet, we don't have critical infrastructure being torn down every hour of the day. Why? How can you possibly draw any useful conclusions about security and threat modelling if you can't answer this very basic (yet deceptively complex) question?
(And you'd be unpleasantly surprised by how many people who work in security professionally, *can't* answer this question)
