It really is quite simple --- find work that you enjoy. This should be pretty easy for someone with your skillset. Just because you "want to help people" or have some moral objection to working for the man does not mean you're entitled to have others fund your dream lifestyle.
There are millions of talented people (some of which I'm sure have noble intentions) out there who don't like their jobs, or at the end of the day are not producing a good result due to dissatisfaction with their jobs. If they want to take a year off, they work more, pick up side projects, cut expenses, and gradually save for it. Is that route really "morally" worse than asking others to pay for it?
