It's not pointless. One of the problems with some of the classifications are that many of you have gotten them confused. To use for example the classification of Life:
You have Plants, Animals, dogs and fleas, poodles, trees and spinach, and apples.
Notice that Plants and Animals are non-specific classifications but are Kingdoms. Dogs and fleas are classified under Animalia but poodle is a specific reference to a type of dog. Trees and spinach are classified under Plants but spinach is a specific kind of plant. Apples is a fruit from a tree.
This is not how some of you have classified the piano.
There are three different classifications of musical instruments, right?
Strings - anything that makes sound by rubbing
Woodwinds - anything that makes sound by blowing air
Percussion - anything that makes sound by either plucking or striking
Which one does the piano go under? It is percussion. It has strings but the piano does not make sound by rubbing the strings; it does so by striking it with mallets. It is struck, therefore, it is percussion. Under percussion, you may be more specific with the classification. Between striking and plucking, the strings of the piano are struck. So it can be further classifed as being struck. It has strings so it can be further classified as a strings instrument but NOT the same Strings under the three different classifications.'
*Percussion
*Strings - Brass - Drums
*Struck - Plucked
*Keyboard
All the way down on the classification table, you can classify it as a keyboard. Don't get it confused by calling it both a poodle and a tree.

And debating which is more aerodynamic? This assumes that there is air in space, which is faulty. There is no gaseous atmosphere in space. Similar to asking "How aerodynamic is a submarine?" You mean HYDROdynamic, right? But for space, what is there? Logic dictates that there is something there regardless of whether we can detect it. So perhaps asking: "How spacial-dynamic is a Klingon ship?" That's like asking, "How many licks to the center of a Tootsie Roll pop?" The real answer is, "It depends on how big your tongue is, how much you are salivating when you lick it, the ambient air temperature, the relative humidity and the water content in the Tootsie Roll pop, how much surface area you are able to lick, how many licks per minute..."
