Of course the Mercantor projection gets country sizes wrong. All map projections get something wrong, because they are projections of a 3d sphere onto a 2d plane.
The trick is to pick the right projection for your purpose. Mercator is good if you want to plot a course when sailing. As it preserves directions. But by doing so it messes up area sizes. Other projections get Areas right but mess up directions.
The trick is to pick the right map for your use case.
