Is there anything that stops the formation of a perfectly frictionless surface? There isn't even enough to type to make a second sentence here.

A frictionless surface is a theoretical surface that has no resistance to motion when an object is placed on it. This means that there is no force acting in the opposite direction of the object's motion, allowing it to move without any hindrance.
No, a completely frictionless surface is not possible in reality. All surfaces have some degree of roughness and imperfections, which will cause some amount of friction when an object moves across it.
A frictionless surface would eliminate the need for lubricants and reduce wear and tear on moving parts, making it ideal for machines and mechanisms. It could also increase efficiency and reduce energy consumption in transportation systems.
Creating a completely frictionless surface is a difficult task as it would require eliminating all sources of friction, such as surface imperfections, air resistance, and molecular interactions. It would also require constant maintenance to prevent any buildup of friction-causing substances.
While a completely frictionless surface does not exist, there are some materials that have extremely low friction coefficients, such as Teflon and graphite. These materials are used in applications where low friction is desired, such as non-stick cookware and lubricants for machines.
