Why does insulators and isolated conductors gets charged due to friction (explain in detail)?

Why does insulators and isolated conductors gets charged due to fricti...
When you charge an insulator by friction, the close contact of two electron clouds (each from a different medium) allows for electrons to be transferred between them.
The number of atoms coming in contact to each other by friction is proportional to the area of the two insulators rubbed together. The whole surfaces can be rubbed . That is an enormous number of atoms.
Yet why can the same not be accomplished with conduction?
Suppose one has a battery, and wire attached to one of the poles. If one touches a metal plate, it will be charged because metal conducts well and all the surface will come into balance and display the voltage of the battery. On an equivalent insulator plate only where the wire touches the surface the charge will appear, a few atoms, depending on the area of the point of the wire,as by definition the mobility of electrons is very low in insulators.
