Everything you mention can be born out of individualism, not just by blind conformity and having any fixed social structure.
Can it really? I feel like this would require further discussion and is not as obvious as you seem to think.
Where is the line between the content of the idea individualism and the political reinforcement of the idea in the populace? It is apart of the fixed social structure already.
Is being governed by a shared idea, not blind conformity in itself?
Capitalism is a great way to have people work in collaboration while still being motivated by their own individual goals.
