Yes, the point is that most people don't want such a world. With very few exceptions, even hardcore libertarians don't want that world. That's why they're arguing that some sort of court system isn't necessarily incompatible with libertarian values. It's pointing out the issue with the "how can you consider yourself a libertarian but support people using a government system, like a judicial system, when they're wronged? isn't that hypocritical?" argument. It leads to the conclusion "if they're really true libertarians, they'd either let themselves be victims or just take justice into their own hands", and neither of those would be desirable outcomes. The argument would make more sense if, say, the victim had gotten taxpayer-funded federal law enforcement to find and apprehend the perpetrators. But in this case they hired a private investigator, sent a request to the parents of the alleged perpetrators, and filed a lawsuit when the request wasn't responded to.
