You are probably right in general. However, copyright extends so long now though that it's not uncommon for things to be out of print or no longer distributed,

You are probably right in general. However, copyright extends so long now though that it's not uncommon for things to be out of print or no longer distributed, so your only option is "pirating" if you want a copy at all. There's all sorts of weird related scenarios as well. Maybe it's just what I'm personally familiar with but I no longer feel like the typical pirating case is what it was in the 90s, the "free stuff" case. More often now, it's things that someone can't legitimately get otherwise.
