That there's demand isn't necessarily the fault of the user, in many cases it's the fault of industry. At this point, at least for petroleum, it's a feedback loop - we built infrastructure around it, people became dependent upon it because alternatives are limited, the dependence creates demand, and that demand is used to justify continued production.
The petroluem industry then just has to work hard to squash alternatives, as it very much has, thereby leaving the user with little to no choice.
So you changed your beliefs to ease some cognitive dissonance and help yourself sleep at night. Seems normal and expected to me, people do that all the time. These companies actively advertise and lobby to get their product into more peoples hands and quash alternatives.
