And then some other killjoy did the math and realized that if the ring
were to be moved so that the star was no longer in the center, the
situation would not correct itself naturally; if there were no
artificial corrective measures, the ring would eventually collide with
the sun. Roll the credits.
BTW, Dyson himself did not postulate a solid sphere, but a large number
of small bodies which collectively capture all of the output from a
given star.
