Naturally, being in the United States, the rancher wins and stays on his property. The town was happy for him. In fact, they were somewhat cheering for him in the part I saw, though he did have an enemy. Yes, the movie promoted individualism.
I am a person who doesn't like big government, but this movie, and many like it, miss the point. You cannot have a strong community or a strong nation with rugged individualism. It just can't work. A strong nation only occurs when people sacrifice themselves for the sake of a nation. An individualist only looks out for himself. At times the individualist may try to help the nation when it is in her or his best interests. But, at its heart the individualist is only self-focused, and that only hurts any sense of community or nationhood. Individualism destroys marriages, churches, and any sense of community in any organization that includes more than one person.
Our nation is struggling because we value individualism. We promote it in movies and in other media, yet we struggle in valuing other people and in working together as one unit. We have problems "getting along." Somehow, we have to come to a conclusion that the rugged individualist is not what it is all cracked up to be. If you want a strong nation, or any grouping of people, then individualism, the worship of self, will need to be rejected
