Stallman's insistence on unlimited and unrestricted redistribution at a price not exceeding cost is the critical flaw with the free software movement. While I agree that this is good and should be encouraged where possible, if there were a license or some support for persons that allowed access to and modification of the code and redistribution of the code only to persons who were appropriately licensed by the copyri…
This is comparing apples to oranges; you don't lose the possession of software when you share it.
There are times when this kind of sharing is good, but I believe if we were interested less in economic zealotry and more interested in individual freedom to control the software that runs on one's computer, we'd see a lot more people distributing source code. That would ultimately produce a net increase in freedom for computer users, even if the rules say you can only share modifications with people that have a rightful license.
Those that want to license under a copyleft are by all means free to do so, but we shouldn't exclude people that would be willing to distribute source code so that their users can control the program themselves, but who are not willing to switch to a support or subscription based business model. You can't make much significant money selling GPL'd software, you only make money by selling support contracts to BigCo. And that model is not applicable to everyone, even if it works out OK for database systems and Linux distributions.
Whether it's simple to copy or not, it's not simple to implement or design, and implementers and designers should be compensated even if their work can be reproduced at minimal cost after its initial production and release. A car's physical properties that make it much more difficult to copy have nothing to do with whether the hoods should be opened or shut, and whether rightful owners should be free to tinker around inside.
