I don't think that line of thinking will get you very far. You can pick up the ball and run with it in American football but not soccer. You can insider trade in US commodity markets but not US equity markets. Spoofing is illegal in US equity markets because that was the result of the rule-making process. I'd argue that banning spoofing is a good rule for equity markets, but it's not necessarily a good rule in other contexts.

That is exactly my point, see parent comment - "Spoofing distorts the market by making it appear that there is much more liquidity and demand or supply. Distorted markets are, theoretically, bad for various reasons." banning spoofing in different markets/fields isn't necessarily a good thing.
