I find this is at the core of Stallman's criticism of the term "content". We speak of media "content", of "content authors", etc, as if movies, articles, books, etc were just that: content, ready to be commoditized, packaged and sold. And some of it is! But we've conditioned to think of everything as "content" to be "consumed", which is depressing.
Specialization pretty much requires it, and our adherence to capitalism demands it.
You specialize to get paid, and by getting paid you can pay others that specialize to create. And you're right, it's a depressing system, but it's no less depressing than what came before that.
In a similar breath, that may be why we don't heat much of the next generation of Stallman's and instead hear of a looming crisis in FOSS as the old guard retires. Less devs (if they are even pursuing that path down the line) will have the free time to choose FOSS as a path, unless big tech is paying for it to bend ot to their will.
You can make an argument that it is more depressing when the compartmentalization of everything also isolates off community. No amount of individual riches can repair a trusted community to engage with. We're definitely getting lonlier in the process.
And we've all adopted it. Or mostly, anyway.
