I suspect a laser with enough photon energy to life granite blocks of that kind of mass would instantly vaporize them sooner than move them.

Photons will impart momentum, but only a very small amount. This would need a ridiculous amount of power for the laser
Light is a powerful tool to manipulate matter, but existing approaches often necessitate focused, high-intensity light that limits the manipulated object’s shape, material and size. Here, we report that self-stabilizing optical manipulation of macroscopic—millimetre-, centimetre- and even metre-scale—objects could be achieved by controlling the anisotropy of light scattering along the object’s surface. In a scalable design that features silicon resonators on silica substrate, we identify nanophotonic structures that can self-stabilize when rotated and/or translated relative to the optical axis.
