Not only do I agree that the show is likely not tourable due to the set requirements, but I also think it'd be well-suited for Vegas because of the benefits (in this case) of cutting about 45 mins to get it down to the Vegas 90 and ending with the fight. It would maybe even be an improvement overall!
The set is in an interesting dilemma, because the actual mechanics of moving the ring are pretty easy, it's the variability of touring to different houses that has to be the catch. Different stage heights/row dimensions/seating arrangements... they'd have to do a lot of work at each stop to make it worth it, most likely more than possible.
Words don't deserve that kind of malarkey. They're innocent, neutral, precise, standing for this, describing that, meaning the other, so if you look after them you can build bridges across incomprehension and chaos. But when they get their corners knocked off, they're no good anymore…I don't think writers are sacred, but words are. They deserve respect. If you get the right ones in the right order, you can nudge the world a little.
