Why the product rule?

Hello dear community,

I have a question regarding the product rule. When differentiating sums, the sum rule is used, which is differentiated summand by summand. Now, when I consider a product, I might also consider simply differentiating the two factors and that's it. I understand the product rule myself, but I don't know why the above is wrong.
