A few thoughts:

What makes "camo clothing" so expensive is NOT the color or pattern. It's brand names, scent control, waterproofing, silent materials, warmth technology (more heat with less bulk), etc etc. Some of these are important, some aren't.

Why would you NOT benefit yourself? Camo won't hurt you, so if it happens to help in the least, why wouldn't you wear it?

Camo breaking up your outline has NOTHING to do with how well the guy in ASAT looks standing against the trunk of a tree. It has to do with how well he blends in standing up in the open, displaced from the background. The most important aspect for a deer hunter is blending DEPTH. You'll notice when a deer thinks it sees something, it will swing it's head side to side, up and down, to try to spot whatever it is that it thinks it sees. What it's doing is forcing parallax, i.e. the background will move behind the object. Good camo will distort the edging to their poorly defined eyesight, which helps merge the hunter with its background.

Anyone can blend in when they're laying in the bush. A lump in the grass looks like a lump in the grass. But, when a bow hunter is kneeling 3ft from the base of a tree, and a deer swings its head to pick them out, that's when your depth defeating camo is important.
