Why area of surface has no role in motion due to friction, Physics

Friction is a microscopic constant and so macroscopic level area does not matter.

But area would matter if the object we''re putting under study was microscopic, which isn''t in our case.

Because friction depends only on cofficient of friction and roughness of the surfaces and it is independent of the area b/w the surfaces
