Nobody at this level writes a paper like this, asserting a specific causal relationship, without considering exactly the questions you raised. The authors address your concerns. It's possible they did so poorly. But that is the case you would want to make. I'm tired of reading these low-effort takes on HN.

HN sees an awful lot of low-effort "research", which merit only low-effort takes.

This comes from the National Bureau of Economic Research, a well-respected organization. Even if you read only the title, the presence of "nber" in the URL means that it's worth more than just a hot take.

If the link were to substack, or phys.org, or various other content mills, then the HN kneejerk reaction would be warranted. Or rather, what's warranted would be silence, but at least the kneejerk reaction wouldn't necessarily be disproportionate to the quality of the work.
