It could also be argued, that’s precisely what makes you a professional writer lol.

I won’t say writers who don’t make money aren’t writers because that’s not true, but at that point its just a hobby or passion.

People who are bothered by the fact a writer makes a living off of what they do have a lot of internal work to do on themselves. The square root of it is them being upset with themselves for not trying or being able to make a living off of whatever it is they truly want to do in life, writing or otherwise.
