You're assuming it would be cheap. People assumed that with fission too. Meanwhile PV and wind turbines are getting cheaper.

  True. I think it's a reasonable assumption. But it doesn't matter as I don't see there being much competition between it and solar/wind. The latter will be needed to get us to the stage of being able to do fusion at scale anyway. Fusion is such a huge project, I don't believe it can be done without a well-functioning global network of individually thriving nations, and think dealing with climate change is a necessary prerequisite for that. In other words, in my view for fusion to have become useful at scale, I think we already must have decarbonised electricity production (with solar/wind/geo etc). If at that stage fusion is cheap enough to give our civilisation a boost, all the better. If not, we'll be in better shape than looks likely now anyway.
