Something is only weeded out if it is sufficiently disadvantageous. There are lots of examples in biology where mutations are neutral and allowed to accumulate. There is also a lot of junk DNA, and even though we've found that some junk DNA was misclassified, there still is a lot of junk DNA in each genome

Dependence on something that isn't there is disadvantageous by the definition of "dependence". I don't see the point you're trying to make.
