Yes and no.
It is not meaningless, just confusing. There are multiple levels of "organic", and they are that way for a very good reason. As a parent of a child with severe allergies to dyes and preservatives, we must pay attention to those labels, and I believe everyone should understand them, or try to learn.
The problem is the UNREGULTATED labels, like "all natural". That and others are used by companies to make a food appear healthier than it is.
Verified organic foods are not the same as organic, or usda certified organic, and if you ever spent a night in the ER with my daughter when we made an error in a food (such as thinking pursue chicken was no different than organic, or even better, then night we didnt read the fine print on a bag of bread to see they"might" use canola oil instead of butter) you would understand differently. I know i did, and I have had to make a lot of changes I may not have otherwise thought necessary.
Most people don't need to make a change this way, so they don't understand. This labeling system is not perfect, but its better than no labeling requirements.
