"The GBA should be used to sell GC and GC games rather than using the GC to sell the most successful system on the market."
It is selling Gamecubes. GCN sales doubled when the game was released in Japan.
It's actually an ingenius way to sale Gamecubes. People who already own Gamecubes are buying the game, inviting their GBA-only friends over to play it, and hopefully getting them more interested in buying a Gamecube themselves.
"Lets say the average smuck who has a PS2 sees the commercial and wants the game. There is no way he has three friends with GBAs and the money to buy a GC, FFCC, a memory card, extra controllers, a GBA, and a link cable."
First off, remove "extra controllers" from the list. The game uses GBAs INSTEAD of controllers.

"I would rather have just bought the game and been able to sit down by myself and play it like Kingdom Hearts."
