Now, about it being 'impossible to finance big-budget cinema': the elimination of copyrights would hardly have that effect - it would actually make it easier to finance Hollywood movies because the cost of licensing works on which films are based would become zero. In the case of a film like Lord of the Rings - the estate's deal was for 7.5% of GROSS. Take those kinds of costs out and you get a much cheaper film to make.
As for a dystopia being required to enforce copyright law: all that is required to enforce copyright law is for the law to be aligned with the marketplace. In any such case, that means the law is infrequently or inconsequentially transgressed; it isn't the law that is feared it is the enforcement.
As I stated before, the law and the marketplace need to get together. When they do, it'll be a fine thing and won't require crazy DRM or a dystopia.
When the law is aligned with the market people will choose to pay for things. The only safeguard content producers will have is people's sense of reciprocity. This transition will take time but its a transition that can and should be supported by people in the tech startup space.
I'm all for rewarding artists to encourage them to create more work, but I'd rather it be impossible to finance big-budget cinema then have the kind of dystopia that would be required to enforce copyright law.
