Not sure what you mean by shifting goal posts.
I posed an entirely hypothetical proposition that, if this technology could achieve net zero emissions in a more efficient manner (obviously implied), that there would still be many people who hate on it because it would enable fossil fuels to live on, despite the fact that, in that scenario, we would have solved climate change and allows fossil fuels to continue to prosper.
The fact that the technology would be more cost effective was obviously implied. Is it logical that I would imply that a less cost effective technology would be cheaper? No, so why interpret it that way? Does the syntax of what somebody writes always 100% accurately convey their thoughts? No, but its pretty easy for humans to interpret the meaning.
Anyway, I edited the comment for clarity. All the replies debating carbon capture technology have pretty obviously nothing to do with my original comment, and I question how somebody could interpret it in that way. The entire preposition and thrust of the comment was about the hypothetical, nothing to do with specific merits of a technology (very clearly, and obviously)
