This is a fact. Soap is a lubricant and assists with friction but fact remains, a polished surface creates less friction, less resistance. This is science, not an opinion.
Try dragging your finger across a mirror or a glass. And then try draggin a wet finger across a mirror or a glass.
On the polished surface, the friction decreases up to certain limit but increases beyond that, as the irregularities are cut off but beyond a certain limit the surface molecules exert strong attractive forces on each other.
So probably, the ideal surface for shaving is something that is neither too highly polished but also not too coarse.
Totally agree, a perfect smooth surface will create resistance when weather fills the gaps between surface and cavities in skin, the importance of shaving soap is very high, tha is why taking a pass in an area without soap is like skiing graft.
I cannot afford the car of my dreams but I can certainly shave with the best razor in the world!
