My first instinct is to agree with this sentiment. There’s a lot of pretty mediocre photography that gets attention because “naked woman”.
At the same time, you could equally say “that landscape photo is not interesting if you take away the lake”. If you take away the interesting piece of a photo, yeah, it’s not interesting anymore. The fact is that people (but especially men) enjoy looking at naked and near-naked women. It’s a consistently compelling subject. It might be “easy” but it’s still compelling.
