Our Newtonian equations of motion are based on a frictionless world. The real world is full of friction. That adds many levels of complexity to all real world calculations.

Without it we would be in real trouble. For example we wouldn't be able to move around very easily. So you could say it isn't. It does set limits on what we can do though so maybe that's what you're looking for. Eg friction with the air makes driving faster harder but without friction you could get the car to at all. (Jet propulsion from the exhaust fumes are negligible). May need to elaborate further in the question.

Because it is inconsistent and therefore hard to calculate when products are being designed.
