A serious question: Why is this not a poem?

So if a poem must contain something of the untranslatable, then the poem occurs in the mind of the reader, not in the poem itself.  There are certainly poems that I've read at one point in my life and thought nothing much of them; years later they seem like masterpieces.  Shouldn't a poem adhere to at least one or two of the standard rules of poetry?  Something like one word with a lot of white space would be called something other than a poem.  Maybe the word "poetry" has become the catchall for anything that makes us feel.
