What do you think our society is? It's one giant collective, all society is a collective. We build roads, bridges, and schools all for entirely collective purposes. If one were to analyze all societies on Earth objectively one would have to conclude we are largely a collective species. We not only share wealth to pay for collective interests but we do nothing but socialize with one another through some form of technology or in person.
From wikipedia "A collective is a group of entities that share or are motivated by at least one common issue or interest, or work together on a specific project(s) to achieve a common objective."
Can you think of a better way to describe the point of government?
How else was the interstate highway built?
It was not brought about by private investors seeking to capitalize on the nations need for a transnational network of routes (it already existed in the form of trains, also set up by the government but previous to that still, private entities did not invest in such things). The people would benefit greatly from the interstate highway, thus they were a group that shared the same interests. They all paid taxes and elected officials who campaigned on the fact that he/she shared such interest and would enforce it. That's working together on that goal.
