It would make sense that the holes were a convenient way of thinking and speaking about large quantities of goods such that tribes of people might want to exchange. It would be a very visual way of comparing dissimilar goods, like "1 hole has 50 alpaca skins and I need 200 for the shelter I'm planning to build, so I need 4" and "1 hole has 8 baskets of dried fish which can last 3 families thru the winter, so I need 3 for the nine families on the farm", etc.
And I bet they paid a bit of rent for the privilege. Pretty cool.
The first thing that came to my mind:

So is that 1.04 Albert Hall holes?
The holes were created without concern for slope angle or whether there was a drainage arroyo. To me this does not indicate something of secular practical usage. I'd lean toward a ritualistic behavior that had to happen in a certain place, tied with previous performances of the ritual, and performed many times. Question: can they date the holes at either end?
Maybe they were looking for a chest containing jewels, deeds, and promissory notes.

I think this comment is substantially more informative than the article itself:
