The article has so many problems its almost not worth responding

However lets take the basic assertion that it 1.5x10^26 J of
energy for interstellar travel.

The sun's power output is 3.8 x 10^26 J / sec.

So you have to present an argument that the civilization would
not want to expend a few seconds worth of energy to colonize
a nearby starsystem.

It is far more likely that colonization is frowned upon
because colonies are likely to be competitors than
colonization is prohibitively expensive.
