I'll counter with this: widespread lawbreaking only occurs when laws are selectively enforced or not enforced at all. For instance, most people jay walk because they don't expect enforcement. No one in my town expects dog waste laws to be enforced. Those who pick up their poop do so because they're decent human beings. If you wanted to stop dog waste, however, you could step up enforcement to discourage law breaking. This would work with many commonly broken laws. Singapore is famous for this approach. Therefore, I still think commonly broken laws should be repealed. If the law is important, then it should be enforced. If it's enforced, then people won't break it.
Another reason that commonly broken laws should be repealed is that having laws on the book that are selectively enforced is dangerous. They give those in power tools to exploit people they don't like. For instance, traffic laws are frequently violated, but they are selectively enforced. Police use selective enforcement of these laws to target black drivers. There are many examples in the entire justice system where selective enforcement of laws has been used as a tool for suppression. Having this legal grey-area where some people can break the law and some can't is ripe for abuse.
Which brings me to my final point regarding countries that have poor safety for women. In corrupt countries, the law exists as a tool to maintain power of a small group of rulers. The mechanism of this control works in a similar, but more extreme, way to how selectively enforced laws can be abused in less corrupt countries. It doesn't make sense to talk about repealing laws in a highly corrupt setting because our fundamental assumptions about what a legal system should do don't hold up (serving and protecting people, maintain social order, etc). Thus, it's not surprising that the most dangerous countries for women also rank extremely high on measures of corruption. In such places, the law basically doesn't matter.
