Thousands of other things also have carbon emissions: beef production for instance. Or deforestation -- while it doesn't have a positive CO2 benefit, it removes a CO2 sink. The fishing industry has massive CO2 costs that aren't from fossil fuels.

That's 1 thing (the meat industry) whose carbon emissions are both direct (not supply-chain based) and wouldn't be captured by a petroleum+coal producers tax. Not thousands.

Meat production is about 15% of our global carbon emissions, so certainly it can't be ignored - but when the other 85% is coming from activity fueled by petroleum+coal, it doesn't make a lot of sense to throw up your hands to reject a carbon tax because there's "thousands" of emissions source (which ones?) which collectively amount to less than a percentage point of our carbon footprint.

We mustn't let the best be the enemy of the very, very good. A straight-forward carbon tax on fossil fuels is both enforceable, linear, and not that complicated. Can we ignore ranching and meat production? Of course not. So let's tax both.
