Knight errantry is worse than?

From the text:

“There’s no use in beating about the bush and trying to get around it that way, Sandy, it’s so , just as I say. I know it’s so. And, moreover, when you come right down to the bedrock, knight-errantry is worse than pork; for whatever happens, the pork’s left, and so somebody’s benefited anyway; but when the market breaks, in a knight-errantry whirl, and every knight in the pool passes in his checks, what have you got for assets? Just a rubbish-pile of battered corpses and a barrel or two of busted hardware. Can you call those assets? Give me pork, every time. Am I right?”
