I guess I have to disagree this time "There are no rules". While rules do have exceptions, I don't see your examples going against the rules.
If something doesn't pay off (even if you are passionate about it), cut your loses (or as the saying goes: if you realize you are riding a dead horse, get off)
If there is an urge or need for a product, someone taking on this need (even if it's niche) might succeed.
If users are creators it absolutely does matter how easy they can use a product.
These are all rules. The question is, which rule does apply to a specific scenario to what degree and being objective about that evaluation.

I feel like we both agree on the same thing actually haha, just phrased it differently
