It never was, only a corrupt judge can reach that conclusion. Stealing is subtracting an item from one person and adding it to another person, if there are two copies of the item then it's not stealing.
Money is not an object, it's a concept. Also when you forge money you devalue the whole currency therefore subtracting it from everyone. You could argue that pirating a game devalues it, but then I ask you is the game that you paid for any worse because Joe Schmoe made a copy?
that has nothing to do with games. the value of a game comes from enjoying it, not from trading it away. it can be scarce or abundant. wouldn't change a thing. the analogy doesn't work.
If you're the guy that developed a game, you only get so much enjoyment from playing it - and most of your enjoyment from selling 1,000 copies of it to feed your crippling addiction to novelty PEZ dispensers (and paying rent).
On that note, if an indie developer tries to popularize his niche "aardvark slapping game" by selling it for 10 cents a copy, he might quickly flood the entire limited base of consumers that wants to simulate slapping aardvarks, and only makes $100 in the process. By destroying his game's scarcity, even though he discovered an eager niche, he can no longer sell copies at his original price of $5 each - enough to pay rent for the much. That's how scarcity of a game can be valuable.
You're talking about a product. I'm talking about art. You're arguing that free games have no value. I'm arguing that they do and price has no bearing on the value of an art piece.
I'm arguing no such thing. Artists can, but don't always, choose to be generous with the product they make, just like bakers sometimes give extra loaves to homeless people. Would it be true to say that free food has no value? In either case it's an act of generosity. Bakers and artists can both choose to set whatever valuation/price they want on their work, and can adjust if their chosen price point doesn't make enough sales for their goals. It so happens many artists already have enough money, and simply want people to enjoy their work, or spread their name. The vast majority of artists don't have enough money, hence the sardonic meme of the starving artist.
If someone forged 80 quintillion dollars, it would remove the usefulness of $1 from everyone else. (and that is in fact the economic fear that’s generated through excess inflation, something that has happened in many countries)
It can already not be stealing since that requires the stolen object to be in fact a physical (and a moveable one at that) object. Stealing non-physical property does constitute a crime, but it's not stealing.
Note: this is very specific to your country of origin and may not be true for your country or the applicable law in the case of international crime
