How long would it take for sentient printers to evolve and enslave humanity?

also there are other secret advanced technologies negating all the plot holes within my logic

And FYI, the situation today is exactly that save that the big store doesn’t acknowledge credit and the little guy can’t afford the case in court unless the case is extremely clear cut.

All of which has nothing to do with copyright as what you refer to is a case of Trademark which is completely different.

It has even less to do with filesharing as there is no one in their right mind who’d try to make a court case of a person walking by the jeweler, copying the design in the showcase in his own workshop, using his own raw materials, and distributing the manufactured product for free to whoever he likes. which is where your comparison completely falls apart.

If you want to make a pro-copyright case then at least use an example which has anything to do with copyright.

“The few giant companies that own replication equipment would be limited to random commercial duplication and government contract duplication.”

Much like computers then, not so long ago…oh, wait. They’re everywhere these days.

It’s a given that replication equipment will become commonplace. The only “hard” limits is the cost of raw material – printing your own computer or car might very well be feasible, not to mention a lot cheaper than purchasing a finished product.
But given the materials limitation it follows that this will be restricted to enthusiasts in a way copying digital data isn’t.

That’s where you’ll find the limit, no where else. Trying to regulate any mature technology in law is going to end up just like when the french tried restricting the printing press.
