Earlier quoted context omitted.
What business model would you suggest, that is capable of financing the TV and films we like to watch? I'm not aware of anything that works in practice, except for legally enforced copyright for at least a handful of years. And enforcing copyright means making torrenting etc. of infringing material illegal. (Of course, whether it should be 5 or 10 or 20 or 50 or 100 years is a separate matter.) And copying the music…
To play devil's advocate, if there is no business model capable of supporting something, it should die. I like tv as much as the next person, but its hardly sacrosanct.
Electronic media are a viable business as things stand, so you must be considering whether they would continue to be viable without the sort of laws being discussed here.
Whether any business model is viable is relative to the laws in effect. Without laws governing issues like property and contracts, a great deal of today's commerce would be infeasible. Without labor and fraud laws, all sorts of exploitation would be the norm. Without either, exploitative practices would be the only viable ones, but they would not be particularly productive - that is how things have been through most of human history, and continue to be so in parts of the world. There is a lot more at risk here than TV.
On the other hand, the current law in this case strikes me as excessive, reflecting the anti-democratic influence businesses have over legislation. My point is that there are no simple answers; the sort of economy that has brought a previously-unimaginable standard of living to a subset of the human race is a battleground of competing interests and trade-offs.
