No, I said nothing about how the business model works, except that I'm
implicitly assuming voluntary trade (you can't extract more from a
given user than her value).  All I said was that you may want to
amortize cost over all the uses.

Why?  Whatever works ....  Probably a good answer *will* depend on
lack of rivalry, but I don't see why you should reject an answer that
happens to work as well for rivalrous hardware as it does for
non-rivalrous software.

The point was to exemplify extensive vs. intensive, not to claim
software is like labor.  The point is that on the intensive margin the
cost of software is (very near) zero, while on the extensive margin it
can be extremely high.
