A receiving antenna, when matched, reradiates half the power it receives.

Yes but that ISNT ANY REAL POWER in the EIRP restriction sense.

It's real power, but that power all comes from the impinging field; it's
not contributing any new power. So you're right that the EIRP
restriction doesn't apply. The receive antenna reduces the amount of
power in the field by the amount delivered to the antenna's termination,
plus any losses along the way. The intent of the EIRP restriction is to
limit the amount of field strength added by a transmitter.
