Are you also complaining about other parts of societal funding that does not benefit everyone? You could argue about so many things that might not affect you directly (schools, police, roads, …) but at the end of the day you may also profit indirectly from those as well (more educated people, fewer crimes, proper goods distribution, …).
Schools? Police? Roads? Seriously? You gave probably the worst examples you could have. You only missed firemen and hospitals.
But even then, why so expensive? It is a lot of money. Germany has 80 million people, assuming 4 persons per house, that is 20 million homes times 18 times 12 is 4 billion euros per year to pay for shitty tv shows.
How could you possible live in Germany and not benefit in someway from the roads? And everyone pretty much relies on the existence of the police/hospitals, even if they rarely need their services.
A million miles from what is mostly a luxury good with lots of competition.
