I don't think it's just a question of uniqueness. There's still distinct cultures across the planet, which affects architecture, furniture, kitchen equipment (and many other things).

Some people might reasonably expect when traveling thousands of km to find different kitchen styles/utensils/recipes. Not everyone wants to be assimilated in a global tasteless culture. (see also, memes about how late-stage capitalism made everything bland and colorless, from cars to electronics)
