The idea that one could create an utopia is pure rubbish.

Let me explain why: An utopia society can only be created by making a code of laws and behavior that separate it and make it “better” than all other societies. This code must be followed by everyone in order for the utopia to be successful and the code must be strict on what is acceptable for the utopia and what is considered part of non-utopia society.

This is where the problem lies. Since the utopia has to be so strict about what makes it what it is, it ceases to be able to change. This lack of change means that it will always be the same while societies outside of it evolve with new discoveries and altered views on behavoir. It will not take long before the utopia society becomes old, weak and obsolete. The very thing that originally made it strong will become its greatest weakness. Without being able to alter or expand itself with changing times, the utopia will soon fall to other freer, more advanced societies. Therefore there can be no true utopian societies.
