I don't agree that women are valuable property. If anything, men are the property, but I really don't think the concept of ownership easily applies here (in reference to men/women, not bitcoin). As previously stated, men are looking for loyalty, and women are looking for security, in most cases. The two concepts do align, but not always. Your point about concentrated risk is a good one, though, as a man may never own anything, while a woman will seek to own everything until she assuages her need for security.
