Indeed, that's exactly how we used to talk about it: if you can just postulate some initial asymmetry, the question to answer is why it's small.
We don't think this way anymore because we're fairly sure inflation occurred, and its exponential expansion rapidly dilutes away any initial asymmetry. So we need a way to generate asymmetry after inflation ends.
