What about a whole wind farm? Structurally they’d be fine because it’s just the same forces in the opposite direction, right??

I see two problems with your assessment here.
The gearbox is not going to be an issue. It will be very low torque if you try to drive it from the generator side because of that reduction. You’d have to spin it very fast but it would be low torque. The gearing makes it easier, not harder, like a car in first gear. (Or, from the power generation perspective, like engine braking in first gear.)
The blades aren’t running in reverse. You’d rotate the shaft the same direction as when it’s generating power.
