I never reset my island and I never reset my town in NL either. I did end up buying another 3ds game cart to just make a second 'mess-around town', but I never actually did anything to that town. It kind of just collected dust lol.
I don't think I would bother to redo my town or island with the same level of focus if I were to reset or lose it.
