It's a property based on the premise that not just any made up number is equally good as a valuation...
The very definition of "valuation" points to the underlying "true" part -- valuation means an attempt to guess at the value of something.
It might not be possible to have a perfect guess (because nobody has all the data or knows all the future events that might affect it), but it's very possible to know a valuation if BS and critisize it.
Would you buy a Denny's dinner in rural Nebraska for 1 billion dollars?
