It might be in the long term, but the same can essentially be said for nuclear (fission) power – the materials cost is low (compared to fossil fuels), but due to the extremely high capex needed to build a plant it's considered expensive.

I think the first ~50 years of fusion projects are likely to be very expensive and I'd expect that reputation to stick.

Depends on the return. Solar was too expensive until it was a better investment then a coal plant.
