18, jobless, parents are cutting me off?

Hey! So here is the situation: I am 18 year old high school senior, I am living at home, and I am jobless. About a week ago, my mom informed me that my parents were going to quit paying for things like gas, food, clothes, etc. I am totally fine with that, in fact, I would love to have a job. However, my parents still will not allow me to get a job because, according to them, SCHOOL is my job (I have like a 3.9 GPA overall).

A little hypocrytical on their part considering they want me to pay for my own stuff yet won't allow me to get a job.

I require not much. I could make do with 200 a month (most of that for fuel.)

What I am asking of YOU, fellow YouTube Answerers, is how can I make an income without having a job? I was maybe looking at Associated Content for writing articles because I love to write and I'm actually good at it. Anyone have any experience with that or any other ideas?

Please keep ideas LEGAL. I don't really feel like going to jail for drug dealing or prostitution (sorry, that was a bad joke on my part.)
