I find it amusing how often people who consider themselves libertarian, etc, argue for some of the most fascist regimes imaginable.
If you reframe it the discussion as "lots of you will lose your jobs over the next 50 years, but your grandchildren will have about the same employment rate as you, and higher quality of living" then you can start to have a more meaningful argument about how to manage the short-term side effects and the long term benefits.
Similarly there's debate as to the long-term viability of monopolies, as well as government regulation. If in the long term monopolies fall apart on their own and government regulation turns to regulatory capture, then you can see the economist's opposition to trust-busting.
Also, having ten inefficient suppliers is often better than having one very efficient monopoly — because it is usually also efficient at overcharging.
If the incentives are perfectly aligned and there is a medium term success or failure to consider, relative advantage works as advertised; but this will be closer to three equal startup co-founders dividing the work in the early stages than to international trade.
