The saying "everything good must come to an end," does not mean much if there was nothing good in the first place. This is the case with pretty much every single utopian society that has utterly failed, do to the fact that a utopian society has not and will never exist.
It is not possible to be apart of a utopian society once everything starts to fall apart, because of that one person who convinces everyone else that the way they were told to live is wrong.
The reason that a perfect utopia cannot exist is perfectly described by both The Giver by Lois Lowry and 1984 by George Orwell.
In the book The Giver, Jonas lives in a society all based around sameness. No one in the community knows anything related to how people are supposed to live. a good quote to show this is, "Our people made that choice, the choice to go to sameness. Before my time, before the previous time, back and back" (Lowry 120). This quote shows how this specific community has tried to use sameness as a way to create a utopia, but the thing that is wrong about that is being different is sometimes the best way.
The book 1984 is all about a utopian society based on somewhat of a dictatorship ran by "Big Brother". The main character Winston Smith finds a journal that he writes in throughout the book as his way to escape and be free from his community. In his journal, Winston writes, "They always shoot you in the back of the neck I don't care down with big brother" (Orwell 13). Another reason that Winston is writing in this journal is to rebel against Big Brother and what he has turned the community into.
To finish off my argument, no utopian society can exist because of not just every point that was just made, but mostly because everyone is different. Everyone knows that there is no such thing as something that is pleasing to everyone.
"Perhaps the greatest utopia would be if we could all realize that no utopia is possible; no place to run, no place to hide." - Jack Carroll
