I find it useful not to think in terms of labor but capital.
Labor is just the act of transforming and mixing the capital that you own, to form new capital.
You can only own capital. You cannot own labor because labor is an action and not a thing.
Hawker, when you pay your computer programmers to make a product, do you really think it is a product of their labor?
Really? Do they start from scratch and write it in machine code?
No, presumably they use a higher level language such as C++. Well, C++ is information capital that was created by somebody else. Do you pay the people who made C++? C++ itself was created from previous capital. C++ was written in assembly language. Do you pay the people who wrote assembly language?
Presumably your programmers use libraries. Presumably they use design patterns. Presumably they use concepts like recursion that were invented by other people. They make liberal use of information capital that is not owned by you, without compensating the creators.
What percentage of the final product is really a result of your own effort rather than the effort of others?
You claim exclusive ownership over information capital the same way you claim exclusive ownership over you car. I will respect that the day you grant others exclusive ownership of information capital, ie the day you write all your software in machine code and use different programming methods from the ones taught at universities.
Bro' you can't win whatever logical argument you bring.
It's like arguing with priests that god doesn't exist. You can't win. You can't win not because you aren't smart enough but because he will loose all his power if you do.
In the end it's only fiction like all the laws . and you are capable to not believe it . Just be cautious .
There will always be fanatic believers that scream blasphemy and will want to burn you on the stake , when your beliefs don't agree with theirs.
There is no god , no state , no law , no IP , just people that believe in their existence and people that profit from their beliefs.
