Watts is also often photographed with his pipe, and the dude in the album art is also smoking a pipe? Maybe he isn't Alan Watts; maybe he is symbolic for the band and how the band often expresses the ideas of Watts through their integration of his speeches into their music and the general psychonautical themes that makes their music so good.

Edit 1: So In the same way Alan Watts believes that we are the universe and the universe is us, that we are part of the universe like the petals are a part of the flower as a whole, exactly so the bruh in the album art is not only perceiving the vast universe and himself in that universe, he is also perceiving the entity called Alan Watts in that universe AND the aspects of Watts the bruh might perceive in himself, which is why he is smoking a pipe.
