Of course a human statue can stand. There are many examples around
You probably mean "why can't a human statue not firmly attached
stand?" It can, statically. However any small horizontal force, like
the wind, will tend to topple it. We react by contracting muscles to
shift our balance for small forces and by moving the position of our
feet for larger forces. When the forces get strong enough, we fall
over. Statues have a very difficult time responding to outside
disturbances so either their feet are firmly fixed to the ground or
they fall over much more easily than we do.
