Yes, but in this case it seems there is still some(!) science to be verified and/or worked out, not just a matter of money and working out operational efficiencies.

Even once they demonstrate fusion and viable levels of power extraction, it seems there would still be an issue of what is the level of "wear and tear" (incl. any radioactivity) of the fusion chamber - which it would seem may ultimately be a matter of try it for an extended period of time and see.
