That's because you haven't done that work and don't value it.

Women in agrarian societies do difficult manual labor like hauling water, milking, preserving food, tending livestock, laundry. Laundry before machines was backbreaking work nobody wanted to do, which is why the poor did it or women took in laundry if they needed money. If you had a hand free, you spun wool.

Also, they did all that while constantly pregnant or nursing, which is really hard on the body. Sure, women didn't have to go to war, but men didn't have to live with the fear that this year's baby might be the one that finally kills them.
