> Services like this encourage not knowing where your food, water, clothing etc. is coming from
You don't know where those products are coming from. The ingredients in the food you're ordering have been gathered industrially, processed industrially, probably moved between four different countries, ended up at your city's warehouse, were ordered in bulk by a grocery store in your city, were once again ordered in bulk by your local restaurant, were prepared by a chef you'll never meet, packed by some cashier you probably haven't seen and only then does it reach the delivery boy.
And you're telling me adding one more layer on top of that is decadent because you don't know where your food is coming from? Please. The general point is excellent and worth talking about, but it simply doesn't apply here.
