I agree with what you say, up to this point. EM radiation does take the
form of single photons when it is weak enough.

No. Consider the difference between a number state containing
a single photon, a coherent state containing an averege of
one photon, and a thermal state with an average of one photon.

At best you can say that EM radiation takes the form of almost
all vacuum plus a tiny amount of one-photon state in an incoherent
mixture.

I make no comment on whether this distinction affects the substance
of your argument.
