No, that isn't speculation. That's reasonable. There are stars which produce such great amounts of hard radiation that molecules cannot form, that complete atoms cannot exist except at very great distances from the star.
But this does not have anything to do with the rarity or abundance of life. It just means that there are some places where life is not. There are myriad places where it can be and probably is.
But probability is not evidence, which is what the poster I was replying to claimed.
Okay, let's call it reasonable speculation.
When considering an almost infinite Universe,
the numbers end up big, no matter how small
you estimate the probability of Life.
But the numbers will probably remain relatively small
when compared with the size of the (known) Universe.
