Since there will simply be too many of us to make a societly that is I will say laid back as that. Also in some places in the world there is a way too big population density to make a completly liberal society.
We today simply need and consume a way too much resources by size and variety for this dinamic to work on the long run. (in my opinion)
Plus some societies traditionally like "iron fist". In other words if you have a scattered communities with very strong individualism they will probably be a easy traget for a collective that uses more totalitarian / hard socialistic logic. The age of colonializm is proably the best example of this.
