Choosing a source of indoctrination as better than any other(ie, community, family, culture) is arbitrary or part of the pre-existing indoctrination. State or otherwise, if humans can be programmed what's the threshold for free-will?
Humans naturally have a partially arbitrary nature, as only the minority are capable of effective leadership and commitment to any kind of progression. Most are cowards and will be terrified to commit to anything that they know will place them under pressure. An individual always has free will. And nature itself always chooses the proper "disorder", not order. I know how insane it sounds, but the whole concept of order is binary. Order and disorder are not different. They form some type of totality.
