Absolutely.  The engineers who write electrical codes are very smart, 
and engineers from many disciplines are part of the process. GFCIs are 
required because they make it SAFE  -- people get KILLED by leakage 
currents. GFCIs detect the presence of leakage currents and disconnect 
power from the outlet if there is enough to hurt us. .

Agreed here too.  A GFCI in the loft bathroom in the house I owned in 
Chicago was only about 15 ft from the dipole into which I transmitted 
1.5kW, and it was prone to trip. I replaced it with another unit of the 
same type from the same mfr and that fixed the problem.  I had installed 
them myself when I renovated the house, and I had some left over.
