Well, it is not free money if I have to spend money to protect me against potential future negative outcomes of that free money. And where would the money come from to mothball a plant? Naturally that would be from anti-dumping taxes on the subsidized goods causing the issue, wouldn't it? And I would almost never suggest to tell any other country what to do - even though I would consider that legitimate within the ri…
The free money is the subsidy that is the reason usually avowed for anti-dumping tariffs. Choosing to mothball a plant is a choice, not something that automatically happens if some other country chooses to subsidise one of their industries. Revenues and expenditures are both fungible. In the end one goes into the state’s coffers and the other goes out. In no sense worth mentioning would taxes from anti-dumping tariff…
Sure, in the general case, but I don't think we are debating the general case, at least I wasn't. If this other country just had a ton of useless money laying around and felt particular altruistic wanting to provide cheap steel to the entire world, nice of them. Also people would probably not be too worried about imposing tariffs.
But that is not really the case that people worry about, they worry about countries subsidizing goods to hurt or even destroy your industry and making you dependent on them even if prices rise above what you own industry was able to provide before. Unless you are willing to accept this or at least take the risk of this happening, you now have a link.
If the price difference is small enough, tariffs will equalize the difference and you might not actually collect that much money from them because buying from the local industry does not cost more. If the difference is large enough, you might decide to capture part of it with tariffs and use that to mothball your plants as protective measures and still profit from the additional difference.
Also note that I am assuming that production costs are comparable before any subsidies and that there are no other strategic interests for maintaining an industry locally which of course will change the equation again. Even if that other country can legitimately produce steel at a better price than you, say because it has a lot of easy to mine iron ore, you might still put a price sticker on becoming dependent on that country. If you consider the relation potentially unstable, then you might not want to put all your eggs in that basket.
