Power is not allocated the entire digital multiplex, not to individual

Does not follow.

Nearly all FM tuners in existence today are sensitive enough to
receive any FM signal which can theoretically be received using the
same antenna.  Where they differ is in their susceptibility to
interference and front-end overload.

The iBiquity system uses COFDM, so there is some processing gain in
addition to the analog-domain AGC.
