One can't get to the most efficient energy source without bootstrapping. And dyson swarms may be one of the easier ways to get there. I like this video [1] that explains this pretty well, from dyson swarms to kugelblitz. I do not understand enough from the paper to know the difference between kugelblitz and black hole star lifting though.
