The nirvana fallacy is a name given to the informal fallacy 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.

Example #1:

What’s the point of making drinking illegal under the age of 21?  Kids still manage to get alcohol.
Explanation: The goal in setting a minimum age for drinking is to deter underage drinking, not abolish it completely.  Suggesting the law is fruitless based on its failure to abolish underage drinking completely, is fallacious.

Example #2:

What’s the point of living?  We’re all going to die anyway.
Explanation: There is an implication that the goal of life is not dying.  While that is certainly a worthwhile goal, many would argue that it is a bit empty on its own, creating this fallacy where one does not really exist.
