I agree entirely. I am not for State forcing people to provide services or goods. But, if they are no longer willing to provide them, they shouldn't be able to stop others from doing so either. In other words, if Wizards had taken out the older edition stuff out of circulation, and allowed people to distribute the material, there would be no ethical problem. And intent is important here - they intended to deprive the market of certain goods to pressure customers into buying their newer products; they took out of circulation a product that could be regarded by the market as better than the newer one to force the market into buying new products. What they did was certainly not in the common interest.A State may be able to force a company to supply goods that keep its population fed, clothed and sheltered (if no alternative exists), but to force someone to supply a non-essential is- depending upon your political leanings- facism, the nanny state, communism, etc.
Entertainment IS important. It is NOT important enough, however, that the supplier of a particular form of entertainment be enslaved to the wishes of the populace.
Well you just basically said that once I release IP into the market, you would prefer a rule that I no longer control access to it. Again, this devalues IP immensely. With such a regime, I can no longer sell or license my IP to others who may be better able to deliver it to the public.
if I perform a song at my local cafe, 3 customers and 2 baristas hear it. If I sell it to Sony, that song may be heard by almost 50 people (

Those exclusionary rights are why movie production companies pay $10K $50K, $100k or more for "Options" on scripts. If someone can just walk up and produce a script that Paramount felt wasn't worth doing while Paramount has the rights to it, then those scriptwriters will never see those "options."
I don't think ownership of IP should be knocked down at all, I just am saying that in certain situations, the owner's privilege should not be considered, to favor common interest. I'm not saying in *any* case that favors common interest that privilege shouldn't be regarded, but just that if a supplier no longer wants to perform a service or sell a certain good, then others should be allowed to pick up the slack.
No, see above. What you're proposing is extremely destructive of the value of IP.
Yes, but in this case what you are complaining of is the stealing of your potential profits, not your intellectual property.
The ability to leverage property- of any kind- for profit is one of the essential rights in the bundle. Some would call it the single most important parts. Destroy it, and what's left? Hmmm...the ability to use it for yourself.
That's less intervention than setting the rules that everyone gets to follow.In any case, the external action of the State in granting those monopolies is worth the mention because the State is interfering in the market none the less. It doesn't matter if it is removing the goods from the market directly or giving the right to remove them to third parties, it is still intervention. Now, that intervention is good, but only up to a point; as it stands now, the way the State handles monopolies granted to IP holders is harmful to the market, it's harmful to the common interest. While protection is important to stimulate innovation, it is not positive to go overboard with protection either.
As for harm, take a look at the history mentioned upthread: States that protect IP with copyright, trademark & patent laws have more internal innovation than those that don't.
If all you're saying is that its better to have more products in the market than fewer and that anyone should be able to sell products that have been removed from the market by their creators, then this "common interest" to which you keep alluding is looking more and more like simply letting others benefit from work they didn't do.
Besides, the State has rules to deal with genuinely harmful monopolies- Anti-trust.
