There may not be that many photons involved, but
they are all coming from the same direction, and that does count for
something.

If I'm not mistaken, coherent laser light is all in phase. Doesn't
that cause it to have more energy?

No. The energy is measured in watts like any other kind of power source.
In the case of a laser, it's all concentrated into narrow part(s) of the EM
spectrum. An incandescent lamp, for example, creates more IR than visible
light.
