Oh yes, 100% - if they were to implement a fuel system, then just mining for fuel manually on the existing planets would be incredibly dull. Building something like a fuel refinery on the other hand would make sense - it would even give a purpose to habitats/planetary bases, which are completely superfluous at the moment. At no point in the game did I need to build one, and if the game didn’t keep reminding me that base building existed I would probably have forgotten all about that feature.
