I am not so experienced with pets but from what you said, letting Roro out to explore the world won't be a nice idea. Some animals will always return home when they are let out but some won't, considering your environment too, you said there are many strays, and it's not cat friendly, what if she mingles with the strays and refuses to return home? Or chooses to go out often and not spend more time at home?

Just let her be at home, and if possible get her another cat, so that she will havea companion. I am sure with time she will let go of her desire to explore the outside world.
