According to some claims on this sub: Men are disposable because when women find a richer, higher value/status guy who is "more alpha" than the previous one, she would move on to the next man. While women are disposable based on their physical value (age, looks) and can be exchanged for youthful gf/wife, like for example Timati do it with all of his 3 baby mamas (don't want to mention Leo for billionth time), because men like him can afford to switch the "consumables". But unlike men, women can't do nothing to preserve their value to men, because men value physical apect in women the most, so women become "damaged goods" anyway (aging past 25-27).
