In the end, it
is good for people to contribute for the good of the collective. This can be done voluntarily or it can be done through the force of law. The more it's done voluntarily, the less the socialists can make the case that it should be done through the force of law.
So, to me, the Scouts encouraging contribution to the group is a good thing. It actually prevents socialist encroachment by undermining the argument that individuals must be forced into doing what's good for the collective.
You've missed completely the essence of this article. If, for instance, you are willing to turn over your guns so that the gungrabbers won't be able to confiscate them by force, you are still a supporter of the collective over the rights of the individual. You are an agnostic when it comes to individualism vs. collectivism. And that belies your collectivist soul.
