if pure water is not conductive why would condensation be an issue for electronics?

Condensation isn’t pure water.

There are also parts that aren’t purely gold, and corrosion damage is a concern too.

Isn’t it water that basically turned to vapor and then back? That should get rid of most minerals.
This would require both the air and surface to be free of dust. Maybe in a lab that could be true, but probably not in the real world.
