> On the other hand my using some technology does not prevent anyone else from doing the same. Yes, however, for the same reason people can own summer homes they don't use for half a year and retain that exclusivity - even though it wouldn't disturb the people - is because they worked for that. They built it, or paid someone who did. We allow people to enforce their exclusive rights on property even when it wouldn't disturb them to let others use it. Similarly, if I spend a billion dollars building a piece of technology, I should be able to own that. And decide who gets to use it, even if giving it away to everyone wouldn't disturb me. If someone else built their own version of my software (like building their own summer home) they could give theirs away for free (open source) or sell it. But if they broke into my summer home, rented it out, and then left everything exactly the way it was, that's still illegal because they profited from my property, my work. If you believe in private property (rather than say personal property, which would allow you to own a house exclusive to other people, but not to own multiple properties and only use one at a time) it's hypocritical to not believe in some form of copyright (unless you are advocating for feudalism, where work does not count as value, and the owners of the land or tools worked get the products of the labor by default).
