A balance is required.
What I think
I agree that copyright is not like one off manufacturing. When I got married our photographer didn't charge a lot but made money from repeat prints and copies for auntie. I note today that an experienced pro costs a lot more but you tend to get a CD print quality images (OK not always). The model has changed but this model doesn't work for the movie industry so they still need bums on Cinema seats and DVD sales if they are going to make £100m blockbusters. They need reasonable legal tools to prevent large scale copying which SOPA isnt.
As an amateur photographer I have a number of friends and internet acquaintences who have had images stolen by various media outlets or other large corporations and who have found it impossible to get any comeback because the court system is so expensive. In addition, some of these outlets that support SOPA have also been pushing for Orphan works bills that allow them to re-steal anything that has had its copyright info stripped. Although I do have some images from WW2 I'd like to use for family history but I can't trace the original photographer so even here I have some sympathy.
I understand there are art galleries who have issues because they own a work but not the copyright which has been sold seperately. This can lead to them being unable to illustrate exhibitions and even having to pay publications fees for photos that appear on the internet. Total lack of balance.
So I'd like to see something that protects the actual creators of works, for less time, and not the big corporations. I'd like to see standard fees for commercial use that anyone can get if their work is used and they can satisfy a tribunal they created it. This should be low cost, essentially you pay in proportion to the tribunal of the award. I'd like to see DRM that forces you to pay for the copyright again when a new format is introduced to be outlawed, you should only have to pay costs plus a small admin fee to commercially format shift and free f you own it in another format and DIY. Yes it should be criminal offence to make money stealing from someone else's copyright but it should only be a civil offence for copying if you don't profit.
It should not be possible to deny a third party a legitimate service in order to prevent copyright fraud.
FWIW Every song on my iPod is paid for on iTunes or from a CD I own and I even paid for the copy of WinZip on my PC so I try to practice what I preach.
