No, that is not what I'm saying. I'm saying that were replicators or printers to exist, but the classical economy derived its scarcity value entirely from DRM, I would have no problem downloading "LaBWaRe.CRACKED.stl.rar", or for the intellectual challenge of it, downloading the demo (were there such a thing) and cracking it myself. And since the only thing separating this scenario from one where everybody could have everything they wanted is the artificial addition of DRM, I don't think the majority of the people would feel bad in either cracking or downloading pirated copies, either.
In the current world, at least you can claim that it's unjust to download a pirated copy since it deprives the author of the money they would get if you had bought it legally. However, if the only thing that makes things have monetary value in a replicator+DRM society is that there is DRM, then money only exists as a legitimate way of canceling the DRM. Thus, my pirating doesn't deprive the ultimate authors of their value since they can just pirate what they need, too.
It is true that things will be much less clear in the intermediate period where somethings can be printed and other things not, but the greater the fraction of things you need that can be printed, the weaker the claim that piracy is morally bad will be. In practice, in such a "mixed economy" (scarcity/abundance), I'd probably just try to make open source labware.
