If you and your friends chip, it’ll be a few bucks a pop per month to have your own private server with voice chat rooms and video chat rooms.

I’m sorry but it will be difficult to deliver something that fits all the checkboxes Discord filled without a lot of money behind it.
Following the food analogy, you don’t want a burger, you want a whole buffet with all the foods discord delivered.
