Neutral would refer to some object or circuit which has the same electric potential as the relative object. A "neutral bar," would mean a conductor which has no electric potential. If your body has no electric potential, then the potentials will equal, and no energy will be transferred.
It may be the GFCI breaker is defective. Make sure it is wired correctly. Neutral to neutral bar and ground to ground bar.
Because there is a potential difference between the live and neutral wires.

You should never switch the neutral wire. The neutral of the appliance should be connected directly to the neutral wire leading to the service panel neutral bar.
The term SN refers to a panel or disconnect switch that has solid neutral bar installed. It is a small bar that allows the service conductors to be bonded to the enclosure at that point.
It shouldn't. The open end of a non connected neutral should have the same potential as the voltage feeding the circuit. The only time a voltage will show is when the return neutral is tested with a meter to the neutral bar or the ground return bar. It will then show what the supply voltage to the connected load is. Once this neutral is connected to the neutral bar there will be no voltage shown across the test meter between the neutral and the neutral bar or the ground bar.
they touch all the time
yes they can
Yes, touch bar does work with installing windows with bootcamp but touch id does not work in Windows because incomparability of it.

You can use either thumb to touch the space bar.
the bars normally do not touch each other.
Because there is a potential difference between the live and neutral wires.
Without more information that appears to be a 240 volt circuit. Red & black would connect to the 240 volt breaker, white connects to the neutral bar, and ground conductor from the ground rods or ground plate connects to the neutral bar. Make sure that the bonding screw is in the neutral bar and it is screwed through to bond the distribution panel enclosure to the neutral bar.
the volume bar is at the bottom.
Unless the panel is the Main Panel (first panel in the system after the service feed) all panels have a neutral bar. Otherwise you are missing pieces. If this is the Main Panel, the neutral bar is bonded to the ground by a bus-bar. If this is the case, neutrals should all be connected to the same side of these bonded bars. Electrically it makes no difference, however it is a good practice to keep electrical panels neat and organized. If this is not the Main Panel and there is no neutral bar, STOP, PUT DOWN THE TOOLS, CALL A PROFESSIONAL. This panel is missing pieces and may be dangerous. It is possible to have a panel without a neutral. This panel would serve only 240 volt loads where no neutral is needed, however I have not seen this done in residential applications.
