Discussions of piracy seem to revolve around downloading music and movies. IP that is very transient in nature.
What happens when the line between media and the physical world gets blurred?

When we develop the technology to create nearly unlimited physical goods, say someday we actually do invent the Star Trek replicator, are we still going to create artificial scarcity? Will we insist that people not be allowed to create their own goods even though scarcity could be a thing of the past?

What about the future? What if instant fabrication becomes a reality? What if the future of home building is a giant 3D printer that is placed on the ground and a few days later, boom. New home. Think of the affect that could have on society. Now imagine that such ideas will be hampered by the fact that even though homes could be created quickly and easily, increasing availability and decreasing cost, that somewhere up the food chain is some "intellectual property" owner who says that "printing" out that home without paying him a huge sum is a crime.
In the past, people who owned property were kings. Does the future make intellectual property owners kings? Why is a monopoly on a physical item considered bad, but a monopoly on an idea is considered good?
Yes, the future makes "intellectual property owner kings".
Actually, it's not the "future". Before the rise of the PC and internet the richest people I ever met/heard of still were developers of IP (most had developed patents).
E.g., I've seen or heard of people like the guy (or actually his decedents) that patented the galvanization process or created a fabric 'loop' in use by the textile industry. Mega wealthy.
But these are patents, not copyrights.
I'm not sure why that's bad, or why a (time) limited monopoly of an idea you developed is bad. (See comment below.)
It's hard to comment on your question(s) because copyright/patent law is complicated and there are variables I suspect you may not have imagined.
E.g., you pose your question as though the "3D" printer/machine that can create these tangible items (homes etc) is owned by the person. I can tell you that if the inventor of that 3D machine were my client it would never be sold outright. Never (at least not while the patent/copyright was in force.)
Instead, you would lease it from our company. Your lease fee would depend upon what you used it to make. You make a hammer, you owe a small fee. You make a house or a jet aircraft, be prepared to pay big bucks.
I.e., the 'business model' needs to be taken into account.
I can also imagine a long chain of people taking their cut. Most 'customers' of the 3D machine would be utterly incapable of programming it create anything complex. Therefore the people who set-up the programs for a house, a car, a plane or basically anything with moving parts would probably charge the inventor of the 3D machine a royalty too.
(For the "see below" comment.) I have no problem with patents being 20 yrs. That may actually be a bit short. However, I checked out the period for copyrights and it is well over a 100 yrs, I think too long in most all cases.
