Candide's Personal Dystopia

In chapter 17, Candide stumbles upon a secluded, idyllic city in South America called Eldorado where the streets are paved with gold and precious stones, and poverty is non-existent. Everyone seems to live in perfect harmony. However, Candide voluntarily leaves "this earthly paradise" not long after arriving.

Why?

So far in the novel we have only seen death and destruction, a morbid dystopia where darkness and despair hit Candide at every turn, which in theory means that now that he has come upon Eldorado he will live unprejudiced, "happy" environment. For Candide, the reasoning behind his departure in my opinion is that in the world of Eldorado they will always be no one; they will be like any other inhabitant. But if they leave with the "stones and mud" of the country and return to reality they can live like kings and be revered. They are driven by this, as well as an insatiable desire for adventure and Candide's longing to return to his true love.

We notice through Candide that though people crave for eternal perfection, they seem to understand that utopias are not meant for them. They have always resided in worlds of turmoil, and although many aspects of the two societies are enjoyed and believed to be 'the best of all possible worlds' as Pangloss would say, it is not a place that they truly belong.
