I don't want to let my daughter move out of the home. I don't think she is ready...
What threats do you think your daughter will face when she moves out?
I fear she will fall victim of a crime.
Your adult child is an adult, equal to you and equally capable of making it in this world. Thinking of them as incapable is actually a disservice to them and keeps you in parental caretaking mode.
I'm just worried about her safety.
It's find to feel worried when your child start making it on their own, but you need to know that they will have make it on their own eventually. You need to accept that.
