The author concludes that more theaters should change to repertory theater. This is based on the premise that "everyone", including actors, stagehands, and managers, likes repertory theater.
The author assumes that what stagehands, actors, and managers like is what theaters should do. But we don't know that what these groups like will necessarily be beneficial to the theater, nor do we know whether all these groups like some other form of theater equally as much as repertory. If they did, theaters wouldn't have a reason to pick repertory theater over that other form.

This points out a potential difficulty with switching to repertory theater, which doesn't strengthen the argument that we should switch to it.

If this is true, then switching to repertory theater would make it harder for patrons to attend, which would weaken the argument.

This doesn't strengthen the argument. It points out a potential inconvenience of repertory theater.

This strengthens the argument that theaters should switch to repertory. Not only do stagehands, actors, and theater managers like repertory theater, but repertory theater also allows increased flexibility to meet audience demand.
