But there is a huge gap between a polymer and a self replicating polymer.
Is there, though? What reason would you have to assume that the gap is so mind-bogglingly huge that it couldn't plausibly ever be bridged by oceans full of chemicals over tens of millions of years? In fact, the article I linked to uses a reasonably short self-replicating peptide as its example in the examination of the probability argument.
Indeed, there's no one theory of abiogenesis/biopoesis that's viewed as virtually certain yet. Science doesn't have all the answers of the universe. It does, however, have the means to ask the right questions, and so far we've seen enough answers to partial questions that abiogenesis looks extremely possible. There's no real reason to assume otherwise.
