travelling would be easier if tip culture did not vary so much from country to country.
Yes, but experiencing different culture (including tipping) is half the reason to travel.

I agree on the value of learnign about different cultures. But I don't think knowing tipping culture differences is culturally or humanly particularly enriching, though. But maybe I fail in seeing the implications of that.
