## Nirvana Fallacy
The [nirvana fallacy](https://en.wikipedia.org/wiki/Nirvana_fallacy)
also called the "perfect solution fallacy"
is the mistake made when a solution proposed to replace one existing
is judged against a hypothetical perfect solution
rather than the solution in current use.

> This _nirvana_ approach differs considerably
> from a _comparative institution_ approach
> in which the relevant choice is between alternative real institutional arrangements.
