> All of them require you to grind your own coffee.

I'm not sure if this is one of those weird only-in-America things, but in every European country I've ever visited, you can buy pre-ground coffee in supermarkets, and specialty coffee suppliers will grind the beans for you at the point of purchase. Sure, it might not taste quite as good as if you grind the beans yourself every time, but I wouldn't say all the methods above require you to grind your own coffee.
