Would you call it piracy to yank out the ad insert from a free newspaper and throw it into the trash without looking at it? Because that's the exact analog from the non-digital world. Just because the mode of payment changes with the technical abilities of the medium doesn't change that.
Of course it does, the part where the content creator doesn't get paid and is supposed to according to the rules of the platform is the part where it's piracy.
If you show me how that's physically possible I will concede your point, but until then: No, that's not nearly the same. You can't just selectively block physical ads.
While the comparison may make sense when not thinking it through, print is a completely different medium than digital where comparisons only make limited sense. In this one they don't at all.
Physical media does not track views (directly) or click through numbers, for example.
