Exhaustive, overly-pedantic categorisation of all the impacts of battery production and use can also confuse the public towards thinking that batteries are actually very "dirty" in production and recycling compared to the lifetime of fossil fuel combustion in ICE cars. Fossil fuel advocates could also refer to these comprehensive battery assessments to spread FUD instead of comparing them counterfactually with the effects of keeping internal combustion vehicles and gas power generation running.

So, I think it's valuable to include counterfactual comparisons with fossil fuel alternatives in battery and other clean energy LCAs as a protection against such abuse.
