There's dozens (hundreds?) of different types of conceptual fusion designs. Are you talking about fusion in general or just with FRCs?
In general, there's so many ideas that "don't seem like they wouldn't work" without evidence one way or the other. It wouldn't surprise me that the path with FRCs is more fruitful than tokamaks/stellarators/lasers. FRCs are rooted in the inertial-electrostatic-confinement realm of fusion research which actually does produce neutrons even on the smallest of scales.
The idea seems very nice of course, but most fusion ideas seem nice on paper. The problem is just dealing with the imperfections of a real-world setup. I'm not an expert in fusion and just briefly worked in the field as a physics student, but from what I've learned people still struggle with even producing suitable materials that can withstand the occasional plasma plume (which I think is probably inevitable to happen in Helion's design too) that can deposit 200 MW/m² of energy into the walls of the fusion vessel.
So as I said I really hope this works and makes the founders rich while also producing cheap & clean energy, but I remain at least a bit skeptical.
