Never doubt the power of the written word.  I mean this in two ways, first there is no place that you seek called utopia, it means "no place," so bring yourself out of the use of utopia as a grounding point for your thoughts, use topia for now, "place"; we'll consider it a perfect place. 

Second, there has never been a topia of humanity in recorded history.  In which case I make a distinction between the time before and the time after writing.  Since humanity has learned the written word perfect topia is not possible. 

I do not say give up your quest.  But the answers do not lie in writing because all who have written in alphabet have never known perfect topia.  But. . .what was that before?  What was it that there was before we recorded time? 
 
 

Writing words does indeed put thoughts in a box.  Once boxed they can be typed, categorized, criticized, etc.  In general, once written, the words inherently fall short of the intent.  Small, simple subjects lend themselves well to being written down.  Large, nebulous subjects defy a complete explanation.  It will be incomplete because not everything will get addressed, and most of what is addressed will only contain a shadow of the concept presented. 

An artist is rarely finished with any creation, but would tinker with it forever, trying to capture every possible nuance.  All this would then be for a snapshot in time, and the subject only moments later would be so different enough as to warrant a totally new work.  But then, the artist might never get to the next piece. 

And what DID we have before recording time?  Certainly less pollution, no weapons of mass destruction or overpopulation (indeed it was all we could do to keep alive the children conceived), people were content with less.  But is that what we want to go back to? 

There was little effective medicine, travel was harder, life was much more tenuous, food was not a given for most people (granted it still is not for all people now -- that is something that must be changed -- but at least now enough food is physically produced to provide for all people; distribution is the holdup), shelter from the elements is far better than drafty caves or tents, forms of entertainment are much more involved. 

Few people would choose to go back to what existed before the written word.  The reason people long ago were content with less is because that was the reality of the situation.  A small child even today is fascinated and absorbed by a box or a piece of ribbon.  But if we are able to make more intriguing things now, why should we deny ourselves of them?  Again, the issue of distribution arises, but again, this is something we can change if we choose to. 

Interpersonal relationships have always run the gamut of stable to unstable, friendly to unfriendly, individualistic to group-oriented, even before the written word.  Power would have been an issue even before our species had developed into human beings. 

There would have been struggles, with or without swords or whatever other armaments, and if the pen is mightier than the sword, perhaps it is worth the confinements and limitations of writing ideas and concepts down to spread and develop them.
