The CO2 emissions are not themselves the point, the CO2 concentrations are. The concentration is neutral in time scales we care about from wood/alge/bioethanol/etc., but goes up from fossil fuels.

It’s also fine to burn fossil fuels if you can make long-term carbon sinks from other processes, hence people caring about making carbon-rich rocks or whether dead plankton floats our sinks.

It’s a question of being responsible for the consequences of actions, not outright banning those actions before the alternatives have been deployed at scale.
