If you aren't able to get enough funding through Patreon, then it's simply because you haven't found a large enough or the right audience yet. It has nothing to do with value add. Not every viewer is going to subscribe to you on Patreon. Even the biggest channels I have subbed on Patreon have a fraction of their viewers on Patreon of what they have on YouTube, yet it's more than sufficient to fund an entire well-off lifestyle based on it.
