I can't tell if you're taking the word literally or not. For the sake of argument:
Obviously there is no boat-stealing or plundering involved - no Johnny Depp or kraken here. But separately from whatever meaning you attach to the word "piracy" - illegally downloading creative works is theft. You are not entitled to someone else's creative work under any conditions other than those that they set, period.
Unless an artist explicitly says "here's this public domain artwork, share it however you want" (which some people do!), pirating is stealing - you are taking the work of someone's hands without paying them for it, and it literally doesn't matter if you wouldn't have paid for it in the first place, because the work does not belong to you - it belongs to the creator and they get to set the terms of use.
If you want a game or a TV show or a movie so badly - make it yourself. Put your own effort and time and resources and creative energy into it - then you can set whatever terms you want on its distribution.
Believing that you have the right to take whatever creative work that someone else put their effort into that you can get away with not paying for is one of the most extreme cases of entitlement I've ever witnessed, and it demonstrates an extreme selfishness and lack of respect for other human beings as equals.
I would be very interested to hear what moral axioms could justify the position of "I can take whatever I want from other people as long as it doesn't deprive them of a physical good".
