Possibly the best free thing is free time. Everyone wants free time. But since time comes only in a very limited supply, free time can be, ironically, very expensive to acquire.
For example, some people have to work a full-time job for almost an entire year to earn two weeks of free time. Similarly photographers have to do many jobs to earn enough money so they can afford some free time.
Since free time seems to be almost a luxury, why would any photographer work for free? Working for free, literally or effectively, not only eliminates the benefit of working, it also prevents the photographer from being able to afford free time.
