Piano is in no way the most important jazz instrument. You must be hung up on European heritage.
Jazz and blues are founded in "vocal" expression emanating from the human soul. Wind and brass instruments are perfect for "singing" or "crying out" through a musical instrument.
Piano is percussive. Fantastic jazz can (and has) been created on piano. But sax, trumpet, clarinet are the most important - they allow the inner voice to pour forth much like singing. The players literally sing through the instrument.
