In the EU you're probably looking at the equivalent of $300 on average for a letter like this, and you're more likely to have the disposable income available to do it.

Something like this you can easily do yourself and imo wouldn't be worth the money, however getting a law firm involved in small tasks is a good way to test them with something simple to see if they're any good, and build up a working relationship with one incase you need them for something more serious or time sensitive later on. It's generally a good life skill to get comfortable working with lawyers because at some point all of us will end up in a situation where we need one, and that's really not the point at which you want to deal with that learning curve.

Where I live (EU), lawyers have standard rates for standard stuff. For a run-of-the-mill letter, you're looking at ~ 100 €, but could be 50 if they want to get you as a new customer. Source: A lawyer asked me whether they should write a legalese letter to someone I was planning to sue (work-related) with their help, and explained to me all of this, plus a lot of stuff I had to stress/ watch out for. I knew I had found a good lawyer when they then told me I could also have a go at writing it myself.

Now whether or not the example at hand counts as run-of-the-mill, I don't really know.

The privacy concern is valid, but most people (from my experience) aren't interested in interacting with the legal system in this way, and for these sums of money.

Same to be honest. I can't imagine baiting anyone into something like this. One of the things you learn when you get more experience with the legal system is when, why, and how to avoid engaging with the legal system.
