Actually, Lakshmi should be like our Amazon Sita and when the kiddy devas like Indra, Varun, Surya, Yama come to Vishnu, she should tell them that they ought to stand on their own 2 feet and face the Vritras, the Nahushas, the Ravans, the Hiranyakashipus in this world.😆😆
There's the other possibility that Lakshmi doesn't need to have Vishnu for every Nanosecond of the Kalpa.😆😆
