Achieving stable fusion does not make practical power from it possible. It would necessarily cost >10x fission, and fission is not competitive.
We can be absolutely ,confident that by 2100, there will have been zero kWh of commercial power from Tokamak fusion. It is just barely possible that D-3He fusion might work by then, but it would still struggle to compete. It might find use in outer-solar-system spacecraft.
