Based on an inane interview question that was discussed here on Twitter:

"chmod a-x $(which chmod)" not a particularly likely thing for a user to
try to do directly, but it is conceivable for some sort of script to
attempt it by accident because of a bug, and it would make the system
inconvenient to recover. Since it's almost never a desirable operation,
chmodding chmod itself could simply fail unless something like --force is
supplied. The underlying safety logic is similar to that behind the
existing "--(no-)preserve-root"
