It's on the same level as people using incandescent light bulbs. Well we clear 160k Euros after taxes and have public medical care, and electricity is 10c/kWh here, so why does it matter what bulbs we use?
We live in an area surrounded by grass fed cows, so what does it matter if we throw away 3/4 of our steak?
Without regard to how plentiful resources are in our particular area, being needlessly wasteful is in bad taste more than anything. It's a lack of appreciation of the value of what we have.
For water specifically - it is generally speaking the most valuable resource available, we just don't appreciate it because we happen to have a lot of it.
