Part of what makes the issue of consent murky is that each of the 50 states has their own model/property release statutes. in contrast copyright law is federal law so there is only 1 vesion of US copyright law, not 50 state versions, like there is for release laws. The nuances between states can be kind of subtle.
States that have a strong entertainment industry, like California and New York, also have pretty strong 'right of publicity' statutes.
But in all 50 states it boils down to how an image is used. it is somewhat ironic that model/property release laws are not really intended to protect the photographer. They are intended to protect the model/propery owner and the publisher of the image. It's when the photographer is also the publisher of an image that the photographer needs to have a properly execured and defined releaase for the publication use.
Even more confusing is that when the term publication is used that refers to the legal definition of publication, not the internet urban legend definition of publication. As mentioned above selling prints as art is not considered publication, nor is it considered a commercial use. But, start producing those same prints in the thousands or 10's of thousands, and mass distributing them, and you cross a line into publication and commercial usage.
So you have to be mindful that the model/property release, and publication laws are not as cut and dried as laws like traffic laws.
The best resource I have found that explains the issues in depth is Dan Heller's book -
