@hideki@gameliberty.club making a copy != stealing; stealing requires deprivation. stealing art, in this case, would mean that you were to take that art from someone leaving them without. in the terrible example of the mona lisa, if one were to take the mona lisa, then yes, it would be stealing (assuming it being taken wasn't consensual). you now have the mona lisa, there is only one of it, and whoever had it prior no longer has it and this happened against their will. a better example would be that one had the ability to make a carbon copy of the mona lisa an infinite amount of times essentially for free. they now have a copy of the mona lisa, and whoever had it before also retains their copy of the mona lisa. nobody has been deprived of anything, and no stealing has occured.
