Argentina and Finland are mostly-mountain countries. The water usage there is probably lower, and it doesn't matter (it is not used up in the growing of livestock feed, it passes through), and both countries have large areas where you can't eat the crops that do grow, but cows can.
So you shouldn't take them as examples. That their meat consumption is higher probably actually saves water.
