Nirvana fallacy. The nirvana fallacy is the logical error of comparing actual things with unrealistic, idealized alternatives. It can also refer to the tendency to assume that there is a perfect solution to a particular problem. A closely related concept is the perfect solution fallacy.
The origin of the word nirvana relates to religious enlightenment; it comes from the Sanskrit meaning extinction, disappearance of the individual to the universal. Achieving nirvana is to make earthly feelings like suffering and desire disappear. It's often used casually to mean any place of happiness, like if you love chocolate, going to Hershey's Park would be nirvana. On the other hand, if you're a Buddhist monk, it may take you years of meditating to reach nirvana.
