But that information would be available in the future when the future becomes the present. That said, for practical reasons (even ignoring regulations) it's not possible to extract all meaning from historical data. This is especially true in high monetary velocity contexts. There isn't enough time to perform more than superficial calculations. > Market regulation aim to make the market competitive and fair as > well as efficient.

Market regulations attempt to do so. But regulations also have limits -- including jurisdictional limits. This leads to fraud related issues (which, are -- practically speaking -- another example of market inefficiency). > Even if market regulations eliminate market efficiency it is definitely false > that > market regulations eliminate NP-Completeness How [specifically] would this be false? > Economics is not mathematics—it is a social science attempting to explain > social phenomena and distribution of resources among people. Sure, but economics uses mathematics, and if the math being used is mathematically inconsistent, that means that any value in its results didn't come from the math.
