I took the parent comment to be making the assumption that politically attractive options for responding to emissions and climate change tend to be "market-based" solutions or activities that are picking winners between industries (say solar manufacturers and installers vs. coal plant workers). If there is a choice where there is a "winner" with money on the line there will also be lobbying money put toward that effort and so consensus building is easier.

There isn't necessarily anything nefarious about this, just that it may be incapable of dealing with the enormity of climate climate and also, as OP intimates, there may be a class of solutions that are better/cheaper/more efficient from a policy perspective, but that don't have anyone positioned to gain financially from them and so are harder to garner support for.
