So what if Eggman doesn't need the money. There are tons of people who don't need more, but still try to get richer.
But not Eggman. His goal isn't money in the series at all. He hardly even ever mentions it. He wants power, fame, and to rule the world. In fact, he comes from a world where money isn't exactly a thing or much of it. So he doesn't have that in his roots of desire, he wants power.
