For someone to pass through a solid wall, every single one of these atoms would need to quantum tunnel through the wall's atomic structure at exactly the same moment in perfect coordination.
While quantum tunneling can occur for individual particles, the likelihood decreases exponentially with the number of particles involved.
you would need the energy required to break coulombic repulsion, and to break quark gluon confinement [consult a. einstien r. oppenheimer]
