[snip paragraph about capitalism/FOSS]
I also think open hardware and standards are much more important than software. They mean you can build anything you'd like yourself, while allowing developers to live off their work.
Also: Nobody can (physically) stop you from using electricity in a way that is not "approved" by the provider of your electricity. Of course they can. You can't rig a 330v outlet in your house without permission from your provider. Can't build a tesla coil in your garage either. Draw too much power and they will cut you off unless you switch to a commercial contract, if you're allowed. If I were into bad analogies I'd say here that it's like having a data cap. There is an intricate fabric of things related to economy, work, engineering, politics and society in general, the combination of those what makes electricity available in our homes. Same goes for software - you can't take how society works out of the equation.
