I wouldn't want to discourage you from going independent. There's so much scope for doing things differently outside of ThemeForest -- you can set your own prices, determine your own measure of success, and build the kind of products you value without being tied to the demands of a very particular marketplace.

That said, you should think carefully about how you'll generate traffic at a large enough volume to convert a few sales. There are lots of channels that don't have to involve affiliate marketing, but do take more effort. It's taken a while, but I now have a decent amount of conversions from relevant plugins I have added to the wordpress.org repo. Content marketing is increasing my SEO traffic very slowly over time. Some people lean on commercial upgrades for free themes on the .org theme repository. Others seek out placement in marketplaces like WordPress.com and Creative Market where they have more control over pricing.

You might find this post about increasing traffic useful if you're thinking about making the jump.
