in Paying for content you offer three spurious and unworkable options:
(1) Content could be supported entirely by advertising or product placement.
No, it couldn't, that's exactly the spurious theory that burst the first internet bubble. Advertising money doesn't grow on trees, it is finite and comes from the selling price of the advertised product. If Coca Cola increase their advertising spend to support sales of some content they will eventually reach a situation where people buy Pepsi instead because it's cheaper, and/or people install advert blockers to get the content without the ads, which is equally disastrous in commercial terms.
(2) Content could get very cheap to produce.
So cheap, in fact, that no artists can make a living out of it, and end up flipping burgers in MacD. Result: no more content.
(3) We could levy a statutory fee on broadband connections,
So people like me, who have zero interest in downloading music or films have to pay for the costs of other people's entertainment? No thanks.
If *you* want content, *you* pay for it. You don't pay for it, you don't get it, or you go to jail. Simple.
