And this is why many of these NRPs die. They go from "yeah, that sounds cool" to "oh hell no, that's bullshit" in 0 to 60, all because someone takes an innocuous concept and extrapolates it to its logical conclusion.

This is why GMs need to set the tone in the OP. Is it soft sci-fi with flexible universal laws or is it a bit tougher? These problems can be solved very easily in the OP if limits are set. It would seem to me, that any one of these scenarios would be a storyline or season-long plot line if the players involved agreed. (that is assuming the narrative-driven 'this is a story not a game' attitude towards the RP) "Every idea an opportunity" - someone once said that.
