I would like to note that the expertise of the main author of the paper, Lingxi Tang from ETH Zürich, is in solar technology, not fusion power or plasma physics. I know people outside of a research field can provide fresh look into a problem, but I think his credentials are insufficient to answer the main question he poses:
“If you’re talking about decarbonization of the energy system, is this really the best use of public money?”

I think more interesting article looking at fusion power by an outsider is "Will We Ever Get Fusion Power?" by Brian Potter.
