Aragorn can't pull out a red lightsaber and start flinging lightning bolts at Orcs because some shitty new writer thinks Star Wars is cool. This applies to any rules based work of fiction not just science fiction. You still have to follow the rules you established, or at least lampshade why they don't apply here. The whole 'it's all just a contrivance based on a magic rock' defense doesn't work to defend this shitty writing. They just ignored this because Casey thought that was way cooler than lame spacesuits and didn't even bother lampshading it. The shielding afforded by kinetic barriers does not protect against extremes of temperature, toxins, or radiation.
