  1. The entire Kardashev concept is based on the foolish premise that a civilisation's power requirements continue to scale linearly or exponentially to its technological advancement, also that stellar distances can EVER be traversed in such a way as to to make interstellar travel and energy utilisation feasible. I don't know what the possible rate of expansion could be for an alien civilisation, but the idea that alien races are able to spread across their own galaxy, much less have the means to do so is a massive assumption. Maybe when a civilisation reaches high technological advancement, everything can be accomplished for a billionth of the power we currently use, and that is enough to accomplish ANYTHING that they may possibly want to achieve. Maybe there are hard limits on the amount of energy needed, compared to the amount that can be delivered to the tools that might require it. For instance, travelling at the speed of light. No matter how efficient you are, or how well you can transport energy from source to vessel, without going through dimensions or white holes or other theoretical time/space shortcutting routes, moving an actual object at the speed of light will require infinite energy. Even if you could harness stars, how could that be delivered to an engine consistently enough to be useful outside the star's immediate vicinity?
