Anything that is not yet built is theoretical/science fiction. That does not change the answer to the question 'what would happen if you could apply constant thrust'.
I know where you're coming from; I can smell the crackdom too. It's just that my philosophy is to facilitate much as possible (peppered with caveats and warnings) until they violate physics. I don't see the good in shutting people down on principle.
Anyway, that's two takes on the same question. Good for the OP to see differing viewpoints.
