I question this argument.
At the camera while preparing to make an exposure our perceptions and technical skills are guiding the decisions we make. Data is not infinite, thinking is not perfect, time is not unlimited, humans experience mental and physical fatigue. These factors combine to influence our aesthetic and technical choices. The outcome is unlikely to be perfect, no matter what the price of the materials is.
When visual preview and review tools are added to the camera we are able to inspect the captured image before leaving the location, the opportunity to make further adjustments and make another exposure does not decrease the prospect of a "perfect" image, rather it is increased. I submit that with film this does not happen, we are the weak link in the chain, we are unable to process the consequences of multiple adjustments in real time to the required accuracy, with the result that with no image review the image is more likely to include a flaw rather than less likely.
Data memory is inexpensive. (It is batteries that eat up the dollars)
