That may all be true, but hobos have nothing to lose, and with all people in that situation, it makes them far more violent. Clowns may be more agile and may have a higher tolerance to pain, but that can't save them when a hobo lunges at them with a broken wine bottle and tears them to shreds with their sharpened teeth. Hobos are living proof that what doesn't kill you makes you stronger, as if living on the streets and in boxcars year round with other hobos, no food, and cheap liquor can't kill them, there's no way a weaponless clown can.
