Though your argument is obviously well thought out and brings up a lot of decent points, you seem incapable of understanding the "you are paying the same price for less" portion of the issue.
When you get older and begin to understand basic math and economics, the validity of this argument will become clearer. For now, let me put it in a simpler form:
Billy gives me 5 Apples in exchange for 2 pieces of Halloween candy. You see this and decide to give me 5 Apples as well, but I only give you 1 piece of Halloween candy. Of course you are not happy about the transaction and ask "Why would it cost me five apples for only half as much as you gave Billy?"
To which I reply "Either buy a damned candy factory or stfu and gtfo!"
