Discussing "Taxing every household", that would be undercover communism:
(1) One of your human rights is to have freedom of choice. So if everyone is assumed to use SABC, it implies that your choice is made for you by the "Kremlin" in Tshwane.
(2) Since every household has to pay, the SABC board would be reporting only to the ruling political party, ie. the "Kremlin".
(3) What about blind households, they have no need for a TV? Do they have to pay as well?
(4) They could make it impossible for private TV companies, by simply raising the compulsory license fee to such a level that nobody who earns an honest living (meaning not looting from the state, ie. living according to an individual budget) would be able to afford a private TV channel.
So it is a stupid idea.
