Sunlight is 93w/square foot, this would be under 4.5w/square foot good luck melting something at room temperature with that. I think you have a poor intuition about the difference between point sources and energy across an area.
Anyway, math is math but presumably this is why that’s the legal limit. It’s low enough to be safe while high enough not to be expensive for manufactures.
