Ethics in trading understand, between, dealers, becoming, anybody

Hi,

does anybody understand the key point(s) of the LOS 44.p ?

Why trading is based on word of honor (and not rules or laws) ?
Why trading between buy-side and sell-side traders is becoming MORE adversarial ? If sell-side are dealers and buy-side are traders. It's normal that they are adversial (one looses while the other wins)

I have read the Stalla, the Schweser and the CFAI book and I understand none of them.

Thanks in advance.
