The wikipedia article places it as 16th to 19th century which is a longer time period than Globalism was popular.
If the end of my post wasn't clear, I'm not a fan of Mercantilism but one does need to understand the other side. Although a big critique I have of Globalism is that the gains from trade are not evenly dispersed automatically so countries like the US really need to raise the top tax rate and increase (or at least not lower) redistribution otherwise you get high income equality.
Also, slavery and witchcraft are still practiced to this day although maybe not globally popular.

Economic theories like Mercantilism are on the country level so individuals would still buy stuff because they're not practicing Mercantilism.
On the country level, yeah you don't buy stuff. If your citizens love coffee and your climate doesn't support growing coffee beans then you get a South America colony so now your climate does support growing coffee beans.

At the macro-level sure. However, if the USA had continued to practices mercantilism post-WW2 then we wouldn't have complaints about the lack of manufacturing.
The industrial plants in China would've never been built by US investment because that's literally handing money away to another country. If China doesn't have a factory its irrelevant if their labor is cheaper; the only labor with access to a factory is the USA.
