Just because you enjoy a good book, doesn't mean you can write one. I could perfectly say: I enjoy surgeries and watching doctors removing organs", but that doesn't make me qualified to do that myself. Things are to be left to professionals. Writing is an art, is a craft, it's a vocation, it's like sculpting slowly with words and letting them give them life, it's a talent, it's a relief of the soul of the writer because that's what a write is meant to do: to write.
It's a fusion of minds, the character's mind with the one of the writer together, unified, it's about composing and creating art.
I can't stand why people of this century appreciate art even less than people used to before. Before, you wouldn't see, someone who's not a writer, attempting to take a place that does not belong to him/her. Why? Because they already have a job, and are not meant for that. It's about an innate talent, passion, love for the art. It's not about making money, or commercial rubbish. No. To be a writer is a vocation, something that seeks you, something that is always looking for you, since always. It's not whim. It's about art. It's not something "trendy" to do nor fashion.
Why can't everybody go to their own business and respect the art?
