As for me, I'm all for it, especially since today's technology makes this possible! However, I'm still against the extreme measures mentioned by OP, like dropping any other income and feeding yourself with your work. In such situation it becomes hard to distinguish whether you really just found your target audience, or you needed to subconsciously alter your taste to suit their taste because you were running out of money. Apart from that, it's just that the prospect of living off the support of few people—who are free stop paying any moment—seems a bit risky to me personally (I know I'd abandon any authenticity and start making what people want in this case).
