So let's start by eradicating those ridiculous defaults, too.
You've just ensured that the most popular drink in my next campaign is rice wine. Awesome!
I like those defaults. Anyway, if you get rid of them you need different defaults - or create a purely generic game, which wouldn't be D&D as neither dungeons nor dragons are generic. I like other games' defaults too, like Call of Cthulu's bookish investigators in 1920s New England, or Anime's pink-haired teenagers with super powers (not thinking of a specific game).
