If the owner waits too long and the bearing slips on the
nose of the compressor, that will happen. If the bearing
has not yet slipped, there is no reason the clutch cannot be
replaced with no further problem. In either case, it won't
be any more trouble that discharging and removing the
compressor to install an idler. If the compressor is shot,
he can still disconnect the wire harness and use the
compressor as an idler unless he has already waited too long
to do anything. In a few cases, I have found no damage
beyond a bad bearing and simply replaced the clutch bearing
with no further problem. It is a common bearing for under
$20.

But often the face of the pulley is thrashed where the clutch
friction plate hits - inspect it carefully, there are likely to be
cracks in the webs between the cooling slots. Mine had two out of
four broken IIRC.
If one or more of the webs is cracked, replacing the bearing alone
is futile - the belt surface half of the pulley is going to come apart
from the bearing half eventually and then it WILL take out the nose of
the compressor. It ran about $150 new for the complete pulley and a
fresh clutch plate.
