"Biofuels in use, keep atmospheric carbon neutral."

No they do not. The accounting generally doesn't take into account the full emissions of agriculture, which for corn is particularly carbon intense. Not to mention the downstream pollution impacts of over fertilization, such as coastal dead zones

This is the salient point that is glossed over without so much as blinking.

To get 1J of biofuel-based fuel, how many J of fossil fuel is burned? If it’s like 0.9J then you really have to ask how much carbon is released when turning carbon sinks into farmland, because it will take many many crop cycles to recoup that from biofuels.

That is the implementation detail that makes the whole thing a scam, yes. None of that is fundamental to bio-fuels, but rather a property of it being cheaper to do it that way in our current fossil fuel economy, and people not being interested in looking all that closely because they don’t really care.
