Most actors don’t make much money playing roles in theater, movies or TV shows (obvious exceptions for big name stars), rather they do those when they can get them, but make most of their money doing ads. If that ad work disappeared, way fewer people could afford to be actors and the overall talent pool would shrink.

Same goes for people doing drawn art or photography, the commodified work provides a stable income that allows them to pursue the career and creates space for them to produce genuine art.
