Going back to my point from long ago: I have never in my experience managed a single RP server that used or needed any of these “essential” plugins. And I used to manage quite a lot of them, no brag intended.
While I do get that some plugins are hilariously overinflated in price, there’s definitely not nearly as much of a need for these as you think they are.
Note: a lot of skeptics in the past have questioned what kind of RP servers I run. I have very complex mechanics and metas of all sorts in place, such as an in-depth job system, arms regulation, a free market, and more; all without the need for even free plugins. So those who say they need such excessively fancy plugins for what should be perfectly fine in vanilla, I don’t exactly see as very credible.
