What's the REAL definition of "rare"?

Many of us lament at "rare" terminology in our hobby. And this is the exact argument I make every time someone says something is valuable because it is rare. It's not!! It is valuable because of demand. Every one of these E221s is probably 20x more rare than a T206 Wagner. Yet every one of them is about 1% of the value. (give or take)...and Edited to add, everyone's definition of "rare" will be a bit different. In our space I put the "rare" on things with around 10 or less known.....but even my definition is not set in stone, by any means.
