I don't know - "may have been an inevitable result of the laws of
physics" sounds like a pretty grand pronouncement that isn't actually
backed by our understanding of physics.
That is, it sounds rather mystical. Ironic, that.

The citation shows that the original author commits a common mistake, confusing
energy with entropy. Indeed, it is not the energy that life needs, but the
constant flow through the biosphere of low entropy energy from the Sun (5800K)
in the form of UV and visible light, returning to the same amount to cold (3K)
space in the form of higher entropy energy as infrared radiation. For each
visible/UV photon coming from the Sun, 10-20 times more photons return to space.
Life succeeds to trap order from this entropy flow and thus seems to defy the
2nd principle of thermodynamics for those not grasping that the biosphere is not
an isolated system.
