How would you better model real world transaction?

To be fair, the answer to that question is probably someone's PhD thesis.

Quite possible, but he started with "Captain Obvious" so I hoped that meant he knows other models that are obviously better.

Even if they do know other economic simulations which are better, it isn't a given that a better tool exists for every tool that doesn't ideally meet a need. Of course, you did say "hoped" instead of "expected"...
