The comment was referring to current markets, which is the topic of the OP article at hand. No fossil fuel generators pay for their carbon waste, they just dumps it out the stack. US (but not worldwide) coal pays a bit to scrub its waste of the supernasties, saving thousands of lives thanks to the clean air act. Wind/solar/battery recycling/disposal costs are also not currently factored into the market. The only energy system that specifically puts a fraction of its revenue aside for the back-end that I'm aware of is nuclear via the decommissioning funds and the nuclear waste fund.
