Not quite. True, there are underlying philosophical issues in all of this, but origin of life research is legitimate scientific research. (And so far that scientific research does not support abiogenesis
). But the "can't go back in time and observe" argument is not a good argument (and would invalidate the whole field of forensic science!). We don't have to be there to observe evidence left over from the past and to make inferences from that evidence. And it just so happens that the evidence we do have is not supportive of abiogenesis. Like geochemical evidence, for example, which shows no trace of any "primordial soup" ever existing.
The bigger problem is when scientists forget that abiogenesis remains an empirically unconfirmed hypothesis, and speak as if it's an established scientific fact.
