In some countries, women are more than men. Therefore, it may not be possible for every lady to find a suitable husband. So, as Srila Prabhupada asserted that women could just see Krishna as their husband, I think it makes practical sense. However, again as Srila Prabhupada said that women should get married, I resonate with that idea as women need protection: from the father at childhood, from the husband in matrimony, and from an elder son later in life. If a lady has a powerful husband who is endowed with high spiritual ideals like Kardama Muni, she will be under the protection of such a man, and properly cared for in Krishna consciousness.
