Disney (and friends) spend the GDP of a small country to ensure that my entire life is surrounded by their products and enshrined themselves in international treaties to ensure that it will remain so. I could stop consuming their media, which would require me to withdraw from 90% of all movies and music that my friends and family want to watch, which whether I like it or not is what I would call "my culture".
I don't think this is fair, specially considering that I had no say in this state of things and that changing it would require me to essentially mobilize my entire nation against the foreign interests of the USA.
I don't expect everyone to agree with this point of view, but to call it "intellectually dishonest" feels to me like an unnecessary agression. If anything, I would counterargue: expecting people to either pay a toll to access their culture or to to become "cultural monks" is what's truly wrong, especially when there's an alternative that literally favors the interests of people over corporations.
I have and will gladly pay money for authors/developers that really get me excited, though consuming so much interesting content for free can make me pretty jaded. To a pirate, paying for certain software might as well be giving a donation.
Pirating content is just something people do because it's technically feasible. To silence the cognitive dissonance and justify the behavior towards their peers and reconcile it with the rest of their character (presumably they would not steal physical objects with a clear ownership status), this narrative of a morally motivated fight against the big bad recording company or film studio is employed. It's intellectually dishonest.
