This is apples to oranges. Fusion is not the same as fission. We simply don't know the economics of a viable fusion reactor.

However, we do know fissions cost is heavily driven by safety and regulation. It is very reasonable to assume that fusion's requirements in this area are distinctly smaller.

This is kind of my worry as well. We’ve seen fission become impractical by cost and renewables are much cheaper, so even a successful fusion generator has a high bar. I dream of controlled fusion to not just be successful, but practical
