You are correct. I suppose it is a lot more nuanced.

I believe a sound argument for copyright/DMCA would require:

1. Arguments to be made for the social utility in laws enabling such business models to exist, and

2. ethical considerations that come into play when said laws are violated (for example, a creator operating under the assumption of those laws being followed loses out on revenue when those laws are broken)

I still think there are cases to be made for both of these claims, but this might be one reason why the two sides are so at odds with each other.
