It is the simpler explanation, though. You’re inside yourself, experiencing yourself as the decider of things, the evaluator of things. You’re in a position of making choices (ranging from whether to go to that march for abortion rights or send a contribution to the Defund the Police activists down to whether to make coffee or tea for breakfast). Real, or illusion?
How do you proceed on an hour-by-hour, day-by-day basis if you select “it’s an illusion” as your conclusion?
Either it has no subsequent effect on your choices, in which case it merely gives you a case of cognitive dissonance, or it leaves you feeling that your decisions don’t matter much, in which case you become politically and morally apathetic and let go of the big stuff.
The latter is an outcome that could be considered a desirable one by certain factions. So, admittedly, is the outcome of having people believe they are morally culpable for their decisions and should worry about doing wrong things.
Sometimes it’s even the same type of social faction, depending on the extent to which people can be drawn into internalizing the belief that the official definitions of right and wrong behavior, right and wrong beliefs, right and wrong attitudes towards certain things, are accurate ones. Hence, the oft-referenced establishment Church thingie about free will.
It’s less attractive to that kind of faction if you use your free will to discard the belief that the laws (secular and otherwise) and moral teachings (religious and otherwise) are starting point truths and take a larger responsibility for sorting out right and wrong for yourself.
