Very interesting paper! An alternative explanation would be that RNA has not been assembled "naturally" but has been assembled by a life form (cf chaperone proteins, etc) The questions is then what was this hypothetical proto lifeform made of (what are the minimum cell requirements for assembling custom RNA) and how did this chaperone proteins formed if they were not produced by RNA. Maybe they are much more likely to form randomly than RNA itself. https://en.wikipedia.org/wiki/Chaperone_(protein)#:~:text=In%20molecular%20biology%2C%20molecular%20chaperones,disassembly%20of%20other%20macromolecular%20structures https://en.wikipedia.org/wiki/Chaperone_(protein)#:~:text=In.... see other related biotechnologies, such as CRISPR-cas9. Also as a reminder that proteins are not just subsets of RNA/DNA, there are some proteins in the cell that are much larger than RNA itself.
