I think the problem with finger pointing is that it distracts from meaningful introspection. I think there are far deeper connections between oil and consumption than the "I do my part" crowd seems to realize, from the economics of the logistics industry, all the way down to the fundamental assumption that modern growth-oriented economics and consumption are even "normal" (compared to, say, how native tribes lived eons ago). In other words, merely being aware of the need for unsustainable resources in various cases doesn't fully detach us from the reality that the system we rely on to live is broken.
Sometimes I contemplate the "weird" trees in this forest: people investing into off-grid living, or people stocking up bunkers, or isolated tribes in the middle of nowhere; and I wonder if thinking about regular society in terms of scalable homogeneous solutions isn't in a way similar to breeding cavendish bananas - highly optimized in one specific metric, but susceptible to being wiped out globally by a single unforeseen threat (or in our case, by one of the many potential global catastrophes that scientists have been warning about)
If darwinism applies to civilizations, things ain't looking great for the vast majority of us precisely because we're stuck in a rut talking about ifs-and-buts instead of physically adapting to the logical end state of the trends we see in scientific data.
