I believe that intellectual property is a fiction and that the legal obligation to pay royalties is a bad thing.
My view is based to three things. First, I believe that compensation should come from work. Payment for work that is done on spec, as in the case of a photo library, is not mandatory. I do not believe that Paul McCartney should be sitting on his ass and getting money for something he did in an afternoon forty years ago.
Payment for work that is done on spec, as in the case of a photo library, is not (and should not be) mandatory. I believe that asserting that the law should force people to pay for this category of 'spec work' is a bad idea because intellectual property is a nouvelle fabrication to enrich a certain category of workers.
However, I'm ok with helping workers if it won't make the world worse and, in the case of royalties (and most other forms of intellectual property) it does. I believe that the motivation of being able to get rich off of royalties has encouraged a gigantic amount of awful 'art'. Our culture would be infinitely better off if only people so crazed and determined that they would do it without royalties were producing our cultural products.
(Since Napster, there has been a huge flourishing in the world of music. There are now a billion bands. The variety is amazing and there is a ton of awesome stuff out there. I can't bear to think about the hideous conformity and superficiality of music before.)
I believe that the traditional word 'property' is stretched to the point of insanity to get to the 'intellectual' kind.Property is something that can be taken away. When I publish your picture, you still have it, ergo, not property. Stealing is when I deprive you of something. I possess it. You don't. Not true with a photo.
The so-called value of the pictures in question comes entirely from the people who look at an enjoy a picture or other work of art. It is bizarre to realize, but true. If no one had ever listened to a Beatles hit, nobody would think it was important in any way if you played it to a friend today. I do not believe that the artist is entitled to that money in any way.
(I do think it's a good idea to give him or her money though and often do for artists that I want to keep producing, an inducement, if you will. That's how I like to spend my culture money.)
Which is to say, as a legal/political philosophy issue, I do not think that royalties (etc) are 'legitimate'. I believe that royalties induce bad art and a bad culture. I don't think there's any justice in the claim that the value in a cultural artifact derives from the artist. I believe it derives from the audience.
But there's more!!
Just about every aspect of the modern intellectual property regime stifles progress. Software is the most egregious example. Since this intellectual property era, there are tales of many startups either not getting off the ground or being killed by intellectual property lawsuits. It's true also of every other medium.
Every artistic representation is a consequence of one's experience. These days, a person has to not only be creative but able to do so in a way that doesn't too closely refer to the artistic context of his or her life. That, imho, represents a huge, unfair reduction in the ability of people to do art. Many people that can't hit that high bar could be doing lots of entertaining and interesting things if they didn't have to worry about being sued for using too much of the things that are around us.
Remember, it is illegal to play your favorite song at your wedding unless you pay royalties. And no, there's not some sort of "it's just one song" exception. If it's in a public place, you owe. Even though the song has no value beyond the fact that they played it at an important moment in your life. If you hadn't done that important moment, it would be completely uninteresting and without value.
ps, Your furniture guy comparison falls apart because the person is taking the guy's property away from him. After that, the bad guys will have it and the good guy will not. Real property is a real thing and we had to develop rules to deal with reality. Intellectual property is, even if one really supports the idea, a fabrication. It has to serve a goal to exist. I believe it doesn't.
