I said something very specific about science, which you appear to be using far outside its proper context.
The science says basically ‘media reinforcement of problematic tropes can have actual consequences’. It doesn’t necessarily have anything conclusive to say on what is or isn’t objectification, for example.
So your attempt to say that you didn’t feel like the DiD trope is actually objectification wasn’t really responsive to the point.
And @wysinwyg was perfectly correct in turn to say that what actually matters so far as that goes is whether any real life women feel that it’s a problem. Because if women feel it’s a problem, then guess what – it’s a problem. (It’s after this point where the science takes over, by confirming that invoking something problematic repeatedly in media is going to tend to reinforce, perpetuate and exacerbate the problem.)
Besides which, DiD is just literally, objectively objectifying. As @wysinwyg also pointed out. . Princess Peach or ‘Lady’ from Donkey Kong, for example, could literally be Mario’s wallet or something without significantly changing the ‘story’ or Mario’s motivation. (AFAICT, I’m in 100% agreement with everything @wysinwyg has said - they’ve saved me a lot of typing here by saying everything I would have tried to say. Even stole my MacGuffin line straight from a draft post.)
To maybe add something which @wysinwyg hasn’t gotten around to stealing out of my mouth yet (curse you wysinwyg!), I’d point out that tropes also cut both ways: the reason a trope like DiD is an effective shortcut for a minimalist game like Mario to use is that it does a lot of work by leveraging the power of all the OTHER media which uses the trope. Everybody immediately grasps the plot of Mario in just a few pixels, because everybody knows how the DiD scenario is supposed to go: we’ve seen it before in hundreds of books and movies and Broadway shows, etc. etc.
But that means it brings all the baggage of all those other depictions with it. And a lot of them are much more plainly sexist (or, let’s be honest, downright rapey), especially (but not exclusively, alas) the further back you go. They’re also tied tightly into related tropes like “the hero gets the girl”, which are possibly even more loaded with all kinds of consent, agency and objectification issues.
All of that means you can’t deflect criticism from even something as basic as Mario by saying a few pixels can’t possibly be sexist – because those few pixels are deliberately and indiscriminately invoking a huge cultural macro expansion to do their work, and they implicitly give approval and reinforcement to the whole complex as they do.
