I think I'm a bit uncertain as to whether you're expressing your preferences for how to set up a D&D (or other RPG?) game, or setting out what you think are generally applicable norms for the setting up of games.
If the former, well your preferences are what they are, and good luck!
If the latter, I think you are being more prescriptive than is warranted given we are talking about voluntary participation in a leisure activity. If someone is only willing to GM a D&D game if it's set in their favourite imaginary world with no PC options but Dragonborn paladins, Tiefling warlocks and Human barbarians, well good luck to them too! If you find that game not to your taste, then you're not obliged to play in it and are free to find some other way to spend your time.
