74 * 2^24 = over 1 billion possible MACs.
Nintendo does rely on the wii's MAC address being unique as part of their security model, look at how letterbomb works for example.
The friend code is generated from a bunch of system unique info, as well as a seed value that gets incremented each time the wii is formatted.

Yes we have the code to generate the friend code but it isn't based on MAC.

Well if they have the db for macs, they aren't comparing it to the friend code for account creation.
