We should start thinking about changing the definition of the term, collectivism in dictionary. Here is the most succinct definition of collectivism I would propose:
Collectivism is an ideology based on a deliberate and (sub)conscious decision that there actually exists a thinking, emotional entity called "public" or "people" or "we" or "they" and so on. In other words, it is based on a false assumption.
In a most strict sense, collectivism neither is a physical term nor is about psychological tendency. Whether you like riding on a public transportation or not has no bearing on this term. This is strictly an ethical term and has a lot to do with morality because, although only things that actually exist in this world are individuals and individual thoughts and individual sovereignty and rights, it automatically implies that one has to recognize the sovereignty and rights of a collective body such as government. Therefore, any constitutionalist (not to mention any other statists) is a collectivist since a state constitution usually recognizes the sovereignty of a governing body.
Although Mr. G. Edward Griffin explains about collectivism here,
the stance that he and other constitutionalist take is still a slippery slope to tyranny these people are passionately against. Read "The Market for Liberty" by Linda and Morris Tannehill to educate yourself. With the definition above, you will get a pretty clear idea about how our society should be operated.
Government is neither sovereign nor supreme because it does not exist. Only individuals exist. Each one of you is a sovereign being.
Individualism is based on this idea: Only individual person has sovereignty. Again, it has nothing to do with physicality. It is not about psychology. You do not use this term for being alone or lonely. It is about objectivity, a correct idea and good morality, the complete opposite of collectivism.
Once you see the bad and wrong ideas in collectivism, the belief in authority Larken Rose talks about
is self explanatory because those authorities come from the false assumption that a state is a sovereign being.
