... mention that as
Class B airspace , every plane has to have approval from ATC before entering
the airspace. So if the entire point of the ADIZ is to know which planes are
there,

If you had read the NPRM*, you'd know that is not the entire extent of
the information the FAA/DOD/DHS/TSA/... seek.

then the Class B does that just because you must have permission to
enter Class B and you must have a transponder.

But in Class B airspace ATC must admit aircraft in the order they
call, which limits ATC flexibility, and ATC must provide separation to
all aircraft, which may not be possible.

All it requires is ATC giving
a plane a transponder code and they know who you are.

No, they ATC will not know who you are as they would with a Flight
Plan.

If the airspace has to[o]
much traffic Class B can always deny entrance until traffic is at acceptable
levels. It' simple, it is factual, and it does not make the Congress
Critters think you are a radical ...

The comments on the NPRM are evaluated by the FAA not Congress.
