But you are just presuming you can neatly label the involved and 'third parties' to transactions. You can't, that's the problem. Transactions take place in a context of a society full of different groups. Who is to say who is the 'third party'? Before you can have such a transaction you have to say who owns what in the first place. To do that involves third parties.
So what in your opinion does the government need to do here? In my opinion your original context was to say that the governments were breaking the market, so more government would not fix that problem.
In the broader context, I still see no reason to have government involved in people exchanging and debating ideas. In this case ownership is whomever has the belief or idea. It does not require the government establishing ownership as this is beliefs and ideas.
In any case we were talking about the 'marketplace of ideas'. That marketplace absolutely involves 'third parties', unavoidably so.
Yes, but ideas are not damaging, actions are. So the 3rd party here would simply be people learning about other ideas and beliefs. No regulation needed. I already addressed the children thing, but Ill do it again here, kids are not part of this and should be excluded.
You just have this very particular view of human society, as a collection of individuals in a vaccuum, bouncing off each other one at a time, like particles. That's an idea, but its not one that you can demand everyone else has to share. That's the problem. It's why 'diversity' always has its limits, why you will only get diversity within a certain range, after the ground rules have been set, which by definition prioritize* (the British spell this wrong so I fixed it) some ideas over others.
First I am not demanding anything, so please choose your words more accurately so as to not cause any confusion.
I am confused as the the purpose of your explanation of my stance, because you did not explain how it was wrong. So until I can better understand it, I don't know if I agree or disagree with what you think my position is.
That said, people do interact as individuals. Even in group settings, people can only express things from their own mouth. Unless you are telling me that the Borg Collective has come to earth, and if that is the case then I need to find 7 of 9 right now and will not have any further time for this.
