It's not unneccessary because thats the only argument I'm seeing from the anti licence fee side of the debate. I don't like it, I don't use it.
Some people see the greater good for the whole of society regardless of their personal preferences, others don't want to pay for something they don't think they use, even though they do use a TV
Whoever mentioned the NHS is spot on, the argument about scrapping the licence fee / privatising the BBC is usually made by the same politicians that would scrap the NHS and reduce personal taxation. They are usually from the parties of self interest
So me me me me me me is exactly what is going on here
