All it means is you can say "if life is rare, it's not because these specific small chemicals can't be produced". Which is a rather weak thing to say. It doesn't imply life isn't rare, or that further advancement the existence of these small building blocks is easy or inevitable.
Finding strong things here is going to be difficult. Sometimes you have to take a bunch of weak things to figure out where they lie for guidance.
