The problem is that a laser would not be on a flat plane at all ranges. With just iron sights, you'd have no way of knowing if your laser is actually painting the right target. Optical sights really aren't that expensive - even the RPG-7 has them. Considering an anti tank missile can cost several thousand dollars anyway, it wouldn't be that much an issue.
