No argument here. As a general rule, governments should avoid subsidizing industrial-scale commercial ventures. OTOH, I can see a place for government subsidies for pure research of the science involved, and for some basic (and non-propitiatory) development of the technology. (I.e. — just about the opposite of the way the “green-energy” industry is now supported.)
I agree good science is a legitimate use for government funds keeping those in government honest is a different story.
