I agree that mental overhead is a large factor. The technical challenges to enable micropayments seem inconsequential to me. I’d add that the very act of deciding something’s worth could cost more than the thing itself. For example, an article might be priced at $.01, but it costs me $.50 worth of my time to decide if $.01 is a reasonable price.
