I'm talking defense. Terran is good at turtling. Moreover they can build a CC somewhere else and then float it over to a gold base if they feel it's safe to take it (if not, they can float it over to another mine. Not to mention PF. I feel like this is especially true on maps with central gold bases (antiga, metalopolis). Economically they have the advantage of being able to spend all those extra minerals on marines, whereas for P or Z, mining that much is not as useful as getting more gas.
