I understand what you are saying about houseplants going outside. For me it is just easier to give them summer vacation outside I have about a hundred houseplants and they would get neglected inside in the summer when I spend so much time outside in the garden . And letting them have rain and the hose helps with watering.
I think some are just happier out , the fig trees will set fruit inside but I get larger, and in my opinion tastier, fruit if they go outside.
