And, we all know where free love led!?
'People such as yourself like to shift the focus of this debate on these threads' - I' m sorry! I will try to get back on topic.
Context is indeed the problem. I claim you or any one group advocating any policy regarding trade can NOT know, understand and anticipate every context.
I believe Smith and Ricardo would have said that while disclocations are unpleasant - a free economy and free trade are the best and only ways in which to repair dislocations over the longer term.
The context to me is the dislocation that more and more global trade might bring. Unfortunately, these problems have usually been caused by (probably well intended) industrial policy itself. Where dislocations are large the government and/or local institutions should attempt to find a solution(s). But, the longer you ignore our increasingly globalized world and or attempt to 'redesign' your industrial policy in such a way as to 'save' threatened groups or industries - you have only deferred things that are inevitable.
This does not mean that we do not observe trade policy of other nations vs a vis ourselves. China is predatory in many aspects with trade. We can defend ourselves - but if there is truly a comparative advantage then ultimately you need to adapt.
