I think you may be focusing a little too hard on the monopoly thing. Tbh I only said that in the initial reply to mirror the OPs comment in my response. Sorry, I shouldve been clearer in my other comment where I said they're the only big player. I'll grant you there are others in the market of distributors, and that Valve is one of the few big players, rather than the one big player. My bigger point is more that their business practice is extractive and more like feudalism than traditional capitalism.

And I hear what you're saying. I think you probably make total sense particularly in the eyes of neoclassical economics, maintaining Valve is totally justified and completely in the bounds of acceptable business practices-- particularly according to our current economic system and notions of private property. But I, personally, just don't buy them (pun, erhm, intended?)

For one thing, I think there are several good examples of infrastructure going public. And the other, larger thing, is that this passage from Pyotr Kroptokin kinda illustrates my attitudes toward private property.

The house was not built by its owner. It was erected, decorated, and furnished by innumerable workers--in the timber yard, the brick field, and the workshop, toiling for dear life at a minimum wage.

The money spent by the owner was not the product of his own toil. It was amassed, like all other riches, by paying the workers two-thirds or only a half of what was their due.

Moreover--and it is here that the enormity of the whole proceeding becomes most glaring--the house owes its actual value to the profit which the owner can make out of it. Now, this profit results from the fact that his house is built in a town possessing bridges, quays, and fine public buildings, and affording to its inhabitants a thousand comforts and conveniences unknown in villages; a town well paved, lighted with gas, in regular communication with other towns, and itself a centre of industry, commerce, science, and art; a town which the work of twenty or thirty generations has gone to render habitable, healthy, and beautiful.

A house in certain parts of Paris may be valued at thousands of pounds sterling, not because thousands of pounds' worth of labour have been expended on that particular house, but because it is in Paris; because for centuries workmen, artists, thinkers, and men of learning and letters have contributed to make Paris what it is to-day--a centre of industry, commerce, politics, art, and science; because Paris has a past; because, thanks to literature, the names of its streets are household words in foreign countries as well as at home; because it is the fruit of eighteen centuries of toil, the work of fifty generations of the whole French nation.

Who, then, can appropriate to himself the tiniest plot of ground, or the meanest building, without committing a flagrant injustice? Who, then, has the right to sell to any bidder the smallest portion of the common heritage?
