I'm curious why you say it's not a limited resource.

Although you could theoretically expand the length of UPC every couple years to keep growing, the reality is that all the systems communicating these numbers back and forth need to have a standard.

In addition, printed barcodes need to fit within the area they are designed to fit in, if they were regularly increasing in size it would impact various systems (e.g. conveyor systems scanners, item labels, etc.)
