You can assert copying isn't stealing, but the part where "I have something I didn't have a minute ago, and would normally have to pay money to acquire it, but didn't" is pretty clear-cut.
Just because someone wasn't deprived of the thing you now have doesn't mean they weren't deprived of something of value, and pretending otherwise is a juvenile see-no-evil defense.
