The two biggest issues are actually not software related

I disagree, the biggest issues are related to discoverability, and most certainly software-related.

Peertube has the issue that its not very popular, so creators have to really plug their stuff.

Not necessarily. They only need to agree to allow an instance to mirror their content, and possibly one day contribute something to it in the event that it becomes popular enough. For now, consent is really all that's required. The only revenue they're missing out on is AdSense.

Its not profitable for creators UNLESS they add a way to monetize. Some argue that with secondary sources such as patreon, its not an issue, But I just don't see it.

Patreon is one of many different ways to generate revenue. Most popular Youtubers are diversifying in various ways. The most effective of which is creating their own products and using their channels to promote them. Affiliate links/codes is another way smaller creators can diversify.

I like the ability to post my videos and get comments without getting flagged for whatever on Youtube.

As always, with freedom comes abuse. Youtube has a lot of regulations that can be cumbersome but also can protect creators and users.
