This article does point out why securities markets try to thread the needle. If they allow insider trading, large numbers of investors/speculators won't enter the market - it's a guaranteed loss unless you're an insider. No new money enters the market, and there's not all that much profit to be made. If very strict insider trading rules are enforced, it's much much harder to make really gigantic profits. Mixed incentives.
Counterpoint: casinos.
