I think you're vastly underestimating how slow it is to ship things by sail. Take a look at some of the routes boats had to take to avoid the doldrums and find favorable winds: https://en.wikipedia.org/wiki/Winds_in_the_Age_of_Sail. Having to sail 2/3 of the way to America just to stay in good winds added 3 weeks to a month to every trip out of Spain or Portugal.

Take a look at the clipper route https://en.wikipedia.org/wiki/Clipper_route. To ship goods across the world by sail in any reasonable amount of time, you have to sail way down in the southern ocean, where the winds and seas are incredibly rough and dangerous, and many many people have died horribly. https://en.wikipedia.org/wiki/Roaring_Forties.

We stopped using sails, because people were tired of sailors taking one for the team.
