The definition of utopia in wikipedia gave the usual etymology and then lost it’s way.
It starts:
A utopia (/juːˈtoʊpiə/) is a community or society possessing highly desirable or perfect qualities. The word was coined in Greek by Sir Thomas More for his 1516 book Utopia, describing a fictional island society in the Atlantic Ocean.
From there it drifted into More’s socialistic ideas, Plato’s Republic and several other concepts without drawing the cogent conclusion (conclusions are forbidden at Wikepidia) that Utopia isn’t a “one size fits all” concept.
