It's captured that many people because of fear-based marketing.

Many people believe that organic also means "healthier" or "has more nutrients" and that GMO means "unhealthy". "Organic" acts as a namebrand compared to the "no-name" non-organic products.

On a related note, "GMO free" has actually become a qualifier random companies slap on their products to imply health benefits over competitors. Kamps bakery[0] for example advertises itself as "just saying no" to GMO "for the benefit of the customers". Similar things have happened with "gluten-free", "lactose-free" and vegetarian products.

To be clear: I'm saying that gluten- and lactose-free products are being marketed to people without special dietary requirements who have become convinced that these products are inherently more healthy (just as with "diet" products before, which often advertised e.g. less fat but contained more sugar or vice versa; and with organic and "GMO-free" products which offer no plausible health benefit whatsoever).

5.3% of Germany is 4 million people. And a wealthy 4 million people at that. Organic food is not going to feed China, India, Indonesia, Nigeria, etc.
