Some of the comments here are quite interesting. But among the usual misunderstandings is a very important one. Government as we understand is something outside society. It is perfectly possible for people to get together to protect their property from robbers. It doesn't have to be done individually. But that group which has pooled its resources and to a certain extent its freedom of action in order to obtain a solution at least acceptable to all members, and cheaper than it would otherwise be, never, however you stretch it and expand it, becomes a government. Even if it included every member of a given society, and did what we think governments do, efficiently and acceptably to its members, it would still be a collection of private individuals, not a government, because 'government' is above and outside the 'people'. This shows clearly that governments in the sense that most people use the word do not have to exist at all. They exist, not because the people need them, but because someone will also be willing and able to take power from others and stand outside the subject group. (Government and the state are the same thing here).
Some things, many things, are better done collectively, co-operatively. This does not mean they are better done by government. We are a social species, we do many things together. More usefully, many of the things that we do are a consequence of our being a social species, thus it is natural that many of the things that are important to us are better done together.
That absolutely does not mean that such things are better done by a group of people outside and above the main group, motivated by different desires, largely unaffected by the restrictions they impose on others, who can take money by force from their subjects, and who have no emotional interest, or social investment in the people they control. Socialism, statism presuppose these things, and collectivism assumes that co-operation will not be corrupted by those who love power over their fellows.
