Let's say you want a library to manage the SMTP protocol. On crates.io, of course someone has already taken the "smtp" crate (ironically, this one is abandoned, but has the highest download counts, because it's the most obvious name). Let's say you disagree with the direction this smtp crate has gone, and you make your own. What do you call it? Namespaces solve this problem. You'd instead of have user1/smtp and user2/smtp competing in feature sets. You can even be user3/smtp if you don't like the first two. This is precisely what Java enables too. The standard library is in com.java.*; if you don't like how the standard library does something, you can make com.grimburger.smtp and do it yourself. If you choose to publish to the world, all the more power to you. It doesn't conflict with the standard library's smtp implementation.
