This article tosses together bio fuels and plastics. By conflating the two, they seem to try to create some urgency for subsidizing the creation of both. And of course bio fuels are heavily subsidized already.

This article deliberately confuses things by conflating it with the discussion around bio fuels. Which, as you point out is largely redundant given that we now have decent EVs for literally anything with wheels commercially available. Anything from the tiniest scooters to the largest vehicles operated in the mining industry. And everything in between.

The fallacy with this debate is the focus on disproportionately small parts of the challenge of de-carbonization. If we manage to electrify most road and rail transport, heating (industrial and domestic), some shipping and aviation, etc. that would make an enormous dent in fossil fuel usage. After that we might focus on harder things like plastics. I'm not against people focusing on that now. More power to these people. But put it in perspective: it's relatively small part of the problem. And we have alternatives.

This fallacy is a recurring theme in fossil fuel lobbying materials. By spreading fear, uncertainty, and doubt, they hope to slow down the accelerating implosion of their primary revenue maker: fuel sales. So, they talk up hydrogen and bio fuels. Sponsor studies on the impact of windmills on wild life. Etc. I can't help but look at this article and wonder who payed for it.
