The problem is that there is a lot more to it. Some women's finances and access to money is completely controlled. Law enforcement doesn't always respond and protect the victim (a couple of famous examples include Gabby Petito recently, and the police actually returning one of Dahmer's victims for him to finish off), and social welfare agencies have a much weaker presence in many rural areas.
Additionally, 34% of murders of women are done by an intimate partner. For many women who are being abused, there is a real fear of them being killed. From my experience, looking back, it seems like my mom should have been able to get out of her second marriage much easier, but at the time and the place (a pretty small town), it felt like there wasn't a meaningful escape. Even when getting out and to a hotel, the car had to be hidden somewhere else because it is really easy to drive around a small town and find the vehicle.
Sure, you can get a protective order, but that doesn't keep you alive when the abuser breaks into your house in the middle of the night. That only serves to get them behind bars if you survive the encounter when they come.
A lot of women's shelters are full, and don't offer a lot of quality care. My mom used to take me with her to do Mary Kay style makeup demos for the women at the local shelter. It seemed like a pretty bleak situation, and was filled with fear of being found rather than joy to have "escaped."
Especially if there are children involved, some level of contact and knowledge of location will exist until the abuser does something SO extreme that they lose rights to see the kids. There is often a fear that mothers have of being accused of kidnapping the children if they run, or of running on their own and leaving them with the abuser. None of that that is easy to navigate, and many women in those situations don't know where to turn or what resources they have. This isn't in the UNIVERSE of "just leave, its a choice." That choice can have a LOT of heavy variables.
