It's a direct rebuttal to the false statement "Also for the same reason deployment would be faster allowing a faster phase out of fossil fuels."

Fossil fuels had better be phased out soon, and fusion cannot be available in that time.

IMO, the prospects of fusion reaching a practical state are so remote that even the current level of funding on it is difficult to justify. There are fundamental engineering constraints that render it inferior to fission -- and fission is now going extinct itself, being too expensive.
