An individual copyrighted work is not a "monopoly." It is one choice out of many such works. There is, for example, plenty of competition in the soft drink industry, but only Coca Cola Company can make Coca Cola. Avatar is not the only movie out there, and you can watch any opening weekend as different movies fight each other for consumer dollars.

"Competition" is a wide range of different offerings in a particular field. Claiming that each brand is some kind of "monopoly" because you can't choose something else without getting a different brand is just silly.

If you don't like how Avatar is being offered, get something else. You don't want an IPad at ruinous Apple prices, find another system or lump it.

If you think you should have a right to access a specific, individual product or work of art at the price you demand, maybe you're just having entitlement issues. And "dependency?" You really don't want to go there. Take a closer look at the entire plot of Wall-E.
