WRONG!  unless you consider a rise time from zero to maybe tens of
thousand of 
amps in a couple microseconds DC.

DC blocking would only help in blocking a slow build up of static such
as 
occurs before a lightning stroke or under a cloud that is charged but
not
enough to initiate a stroke.  these voltages can reach high enough to
damage
equipment and would be removed by a DC block, but not a lightning
stroke.
