Probably not cost effective once you remove the massive subsidies and scale of fossil burning uses.
There's alternatives and the sooner we start making them at scale the sooner they'll be cheaper and better than the fossil equivalent, just like renewables and EVs and heat pumps etc.
Note that fossil extraction also has a climate impact, methane leaks etc. even when not burned, though the bribes going to politicians are probably the bigger threat.
I agree with all of that, but it's still the case that carbon in glue isn't in the sky, eh? I don't think we should rule out a role for fossil hydrocarbons as part of the transition to a totally renewable/regenerative (aka "circular") economy.
