I like the idea. Are there legal examples?

In general yes, but there are a lot of fuzzy cases. Inheritance,
prototype-bases languages, languages where types are first class objects,
etc.

Again, I believe the music example can help. Reward is due when the work is
executed. So it works for items that can be executed. Music scores,
programs, in a straightfoward way.  For cars, one can view the construction
and sale of a batch of them as the execution of their blueprint. Similar to
books.
