That's not really new. It seems as if some people try to project "there is life outside of planet Earth". Well, the thing is ... is this question important? You already have life here. Synthetic biology will also progress. So why is it important if life is anywhere else? I don't understand it.

There is nothing magic in RNA or DNA. Granted, right now we can not easily explain how life gets "bootstrapped", but recently there was a paper of self-propagating RNA even of a kind of semi-random sequence; this RNA can just amplify itself. I am sure you can find many more similar examples eventually as well as biochemical reaction processes that can be "bootstrapped" - and I am also sure none of these work on an asteroid. So why is there this strange focus on "life outside of planet Earth"? Some people want research money, that is clear now.

Why study anything new? You survived this far without it, after all :)

How common the building blocks of life are out in the universe has important implications for open questions like the intersection of the Drake Equation and the Fermi paradox which has likely relevance to our own future here on Earth.

...though I happen to think what we know so far isn't comforting in the sense that the building blocks of life do appear to be very common and the most likely reason that we have to ask "Where is everybody?" in spite of that is that the Great Filter is probably expansionist self-destruction of the sort we are currently speed-running as a society.
