> I don't think this is at all "something we all know intuitively".I really do, in the same way that a satisfying nutritious meal feels different after you're done eating it than a meal of junk food does.

I was pretty careful to say that not all "content" is like this (though anything that we'd naturally refer to as "content" instead of a "work of art" is probably telling us something). It's certainly the case that there are books, films, shows, and videogames that are meaningful and enriching. There's also 50 Shades of Gray, whatever Michael Bay's latest thing is, Jersey Shore, and Candy Crush.
The form of the media isn't the point, it's the merit of the actual content.
> These don't "engage our entire bodies, senses, and hands", and yet they can be valuable activities that enrich us greatly.
Sure, not every meaningful activity has to tick every box. But it's good to spend your time on things that tick at least some of them. Binge watching completely forgettable superhero series or grinding pointless quests on an MMO are doing little more than fast-forwarding someone towards their death. I of course respect their choice to do that, but my opinion is that choosing to spend signicant time doing that is infantile, just as eating chicken tendies and soda for every meal is.
> At the same time I don't get a lot out of sitting around in a boat for hours; if I want to be left alone to my thoughts I'd rather be on a walk (which I'd argue doesn't necessarily engage my entire body either -- I'm generally lost in thought and have no idea what my body's doing while on a walk).
I only used those specific examples because those are the ones the parent comment used. Find whatever activities are meaningful and rewarding to you. I just hope you're able to find some instead of burning your free time in a mindless fugue of media consumption which is all too easy to do these days.
> I can play video games without brutally murdering a living creature that feels pain, so that's nice.
If you've ever seen me fish, you'd know that harm to fish is rarely involved. In fact, most days there is no fish participation at all.
