Sorry to be like this, but I don’t think you’re getting it still. Like I said, colloquially Steam has value. And especially in relation to you, the gamer. How much you personally value your games more because of Steam, though, is irrelevant, and Valve creating a new product is similarly irrelevant to what I’m saying. Steamdeck does not increase the economic value of any other product (though, I love my Steamdeck)
Again, you are not the consumer of Valve’s (main) product. Valve’s business model is to sell shelf space to the dev. It’s to allow the peasant into the walls of the city to sell their grain in the market square.
The value I’m referring to is the value inherent in a production of a commodity that originates from the raw materials and labor that workers put into it. I’m talking labor value. It’s the value of the grain that originates in the workers toil and the raw stuff.
Valve might help realize gains from the game, but it is not involved in the production and does not create nor add labor value to the game. Their business model is predicated on extracting rents from developers, the people doing productive labor.
You could maybe argue Valve creates value in the production and maintenance of the commodity that is Steam’s infrastructure and sell it at a fair price. But in this context, the whole point of that infrastructure is to realize the value created from the labor of developers, making it extractive in nature. Do you see what I mean? You’re right back at the point where they’re charging developers a rent to access the marketplace. And the whole thing falls apart without devs (workers) creating a commodity (games) from which to extract value. This is what I mean when I say Steam is not value-adding – not that Steam doesn’t have (colloquial) value.
Does that make sense?

I’ll have to read this a little later but just want to say now thank you for your genuine response
