The point of all frameworks provide a set of idioms about how one should best solve a problem. It's not to make web apps possible, it's to establish an opinion about how webapps ought to be written in Go. Which is different than how one ought to do it in Java, and Scala, and Ruby. It's nice to be able to leverage other people's opinions and established idioms without having to figure them out yourself.
