I believe that of the four freedoms, the one that I would want the least restricted (people -yes, I'd like free movement of people if possible, not just workers), is actually the most restricted, in practice if not in law.

I believe that, especially absent a rather strong political and societal convergence, the other three need to allow for quite significant restrictions (for example, if a tax is introduced on carbon in one country, it must be possible to tax imported goods based on their production emissions).

I would not see them as unqualifiable goods in all circumstances.
