You might be able to, but there are a few problems with that "I am too lazy to write and just want to feed ideas into it" approach.

Most notably:

1. If you don't know anything about how to write, then how are you going to polish up that story and prepare it for publication? How are you going to check it for consistency and ensure it's really saying what you intended it to say? You need some foundational writing skills to be able to work in partnership with a tool like this.
2. Copyright. It's still up in the air who owns the copyright when a piece of art is produced with AI. That will remain the case for at least a few years, while various cases go through various countries' legal systems and some sort of legal precedent re: AI and copyright law emerges. Until the legalities are settled, I wouldn't risk it. Copyrights are how you make money as a writer.
