You're correct but testing some is better than none.
A good primer on why we need testing is the Bunk Police's documentary "What's in My Baggie". In it they travel to festivals testing people's drugs. Nearly every drug they test is misrepresented. Most people believe they have MDMA when they have "bath salts". Even the positive tests may be adulterated or one of several compounds that give similar test results.

Not that MDMA is safe; it's without question a dangerous drug. Hundreds of thousands[1] of people taking unknown substances in unknown quantities is a much much larger problem.
[1]Electric Daisy Carnival alone attracts 150,000 people and runs 3 nights. There are several other festivals of similar size, and dozens that attract tens of thousands per night.
