On the one hand, you gotta admit that adding CO2 to the atmosphere (i.e. being a part of the process that is wrecking the planet for future generations) just for fun is at least somewhat morally questionable. Don’t get me wrong, I do it too, but can you really say that you have a right to contribute to rising sea levels, rising temperatures, and the problems that they cause for ecosystems and for societies… just for fun? It’s a bit of a guilty pleasure, in my book.
On the other hand: I agree that outlawing ICE and mandating electric/hydrogen is over the top. I say this because biofuels can give you 90% of the performance and convenience of petrol, while being practically carbon-neutral. It does not take much to modify an avgas- (or mogas-) burning airplane into an ethanol-burning one. You don't even need a new engine or low-compression pistons. Now that is a law that I would support.
Did you know that in Brazil, about half of cropdusters are powered by certified, ethanol-burning IO-540s? Yes, their specific fuel consumption is a little worse than for 100LL (because ethanol has some oxygen in it, not just C and H), and on cold days they need to prime the engine with avgas so it starts easily… but those two disadvantages are a small price to pay for not wrecking the planet, IMO.
