These business models (Patreon, Twitch subscriptions) have been robustly tested over the last 5 - 10 years, and many people make a living off of it. Are you unaware about these sites and how much money they make? The top Twitch streamers have around 15k subscribers, each at $5 / month, about half of which goes directly to the creator. Do the math and consider switching your career, haha.
