I define freedom as the ability to do what you wish, without causing direct or indirect harm to others. It is also the responsibility to do so. You cannot have freedoms without fulfilling your responsibilities to ensure that society runs as smoothly as possible for everyone.

Utopia for me would be having a society made up of free, yet responsible citizens who contribute to society while enjoying their freedoms. VERY unlikely. Just as unlikely as Communism working in a macro-economic scale.
