Not many people understand that smog, EGR, PCV, and the charcoal canister vent are completely different systems either. It's all "emissions junk". Some of it has benefits and doesn't do squat if you take it off.You're not alone. Not many people seem to understand that a PCV isn't just big brother forcing emissions **** on us.
Again though, race car vs. street car. People know more about race cars than street cars because it's more fun. But a race car driven on the street still has street car problems.
