I disagree. I think it's part of the current social code/contract, not just the law. In fact, the RIAA/MPAA ads say exactly that - "you wouldn't steal a car" - because they know people find property (particularly personal property) to be something we have a right to.
Copyright, on the other hand, is only unquestionable by the law.
Eh. For the purposes of what I said, these are about the same. Laws are indirectly derived from the social code, so just move my statement up a level. You still can't answer the question of how the social code ought to view bits from how it currently views them.
Sometimes the social code is wrong, and those who believe that copyright piracy is bad for society are making the case that this is one of those times. Simply observing the current state of the social code in no way counters those arguments -- although some of them can be countered other ways.
That's the thing: I don't believe they are. 46% (70% for young adults) of the US citizens admit to have committed copyright infringement. Almost no one agrees with large fines or with cutting off the connection for infringers.
I think there's a big disconnect between the social code and the law.
So too must the public attitude towards filesharing define our laws surrounding it. The majority of people have, without caveat, expressed through their actions their belief that filesharing is, and should be, a normal and accepted part of society. This may rankle those whose paychecks are predicated upon the status quo, but it doesn't affect our shifting morals. We are a people who accept and embrace "copyright infringement". It is only once this reality is accepted that the content industry may move forwards.
The important question is, if you take the root beliefs and walk back up the tree, do all of the beliefs come to an overall support of free copying? Then you do that in aggregate for society, taking into account uncomfortable truths about the economics of music production and advertising where necessary and on a level individuals won't when they derive their inevitable personal free-riding preferences. Going from high level feeling to high level feeling ("I like file sharing" -> "file sharing is right") does not work. Almost everyone says that they would prefer to pay less tax too.
To put it another way, there are plenty of things people would do if they could get away with it. Not paying taxes, driving as fast as they want, tossing cigarette butts wherever, etc. Your exact argumentation could be used to say, "Society's views about these activities need to change," but that's not actually the case. All you are observing is that people will take advantage of situations where they can get away with something, even if it's not ultimately good for society as a whole. In no way do I accept the norms that you're deriving from this. Rather, I should say that I don't accept the way you are deriving them. My personal jury is still out on whether I think filesharing is a problem that needs to be addressed more or less forcefully.
The only reason this is true is that the laws say it is. Same as with those patterns of yours -- the laws could easily be changed so that you own the pattern always and forever. It's quite pointless to argue about the shoulds of the situation based on current law.
When we're talking about incentives for production and utility, it actually makes quite a bit of sense to conflate cars and music. They have many similar properties. On the consumption side, you do have to consider the added utility of making the music free, though, because some people will be able to consume it who otherwise wouldn't have paid.
