You can’t just call any market based solution “Reaganomics”, but ok. It’s logically inconsistent to say that carbon taxes are favored by industry and neoliberals, when those very people aren’t actually pushing for carbon taxes. Since neoliberals and industry have a stranglehold on policy and they haven’t done it, I must conclude you’re wrong. Why don’t you cite some of the voices "in the climate movement " that are against carbon taxes? I’m not seeing them. What I see is trust the science, and the desire to build political momentum that will results in the science based solutions coming into effect. Things like ending fossil fuels subsidies, requiring utilities switch to renewables, increasing vehicle emissions standards, incentives for electrification, and yes, carbon taxes.
I’m really curious what your actual solution is here. How are you going to get everyone to leave the oil and gas in the ground? A white whale is something you can’t actually find - seems like destroying capitalism or whatever your vague idea is fits that description much better than pricing in externalities via a tax, something that can very simply be layered in to our market structures with our current institutions (and something that is actually happening in dozens of countries, but is somehow impossible according to you).
