Well you leave out the small inconvenient truth that TRIGA is not power generating. The earlier series of the blog post we are discussing actually talks about that a significant fraction of the cost of a nuclear plant is the thermal power plant part, which is the same as for a coal plant for example. Moreover, actually having to use a reactor for power generation significantly increases the complexity of the design, you suddenly need to heat water, which means two different water cycles which mustn't contaminate each other... And having water involved makes things more tricky anyway because of corrosion...
