Its worth pointing out that per unit energy a lot of money is made making economically unviable cargo ship power, submarine and other military naval power, space ship power sources, diesel-electric locomotives ...
True if you want to replace base load of a civilization size network it needs to be economically viable, but we generate "a lot" of power at higher than market minima. Ironically, "good batteries" are the natural enemy of fusion research.
One fun thing about laser fusion is it theoretically can scale down very low and has a trivial "off" switch making it a good resource for engineering tokamak reactor materials or sensors or similar tasks.
The inner lining of a production fusion reactor is hard to make, so a laser facility would be ideal for research. Which is why we have one...
DT fusion reactors would be terrible for mobile applications, since there are so much larger than fission reactors of the same capacity. In space or mass constrained applications they would be ruinously inferior to fission.
