Refineries consume oxygen
Just what it says. Have oxygen be an ingredient in refining (but not necessarily the arc furnace), making atmospheric planet bases more valuable and adding an engineering challenge in space. Mass refining in space should be possible, but not easy without proper logistics. Let's not abandon our need for planets completely until the mid-late game. As it is, people make one launch into space then abandon earth because literally everything is easier in space.
