Yeah, it mostly is, but some of the assays and analyses of these things clearly show the prerequisites required, and that a lot of the catalytic bootstrapping that would need to happen actually is happening. Of course, a very simple single-celled organism emerging from this is highly improbable, but given billions of years, it at least seems plausible for these systems since they are constantly producing non-functional cell-like structures (sacks o' complex chemicals, really). As someone who was a theoretical chemist at one point in time, I would say that these systems exhibit all the potential required to accidentally produce a primitive organism, though whether it actually happened is up for grabs. It is a more thorough story than goop floating in the ocean anyway.
