According to the United Nations Development Programme, Norway has held down the highest HDI for 7 years out of the last 10.
In conclusion: intelligent regulation good, apparently people like Deck Knight and yourself can't drive that through your skulls.
I think the trouble is that "regulation is rarely intelligent."
Let's face it-- the greatest businesses of finance are backed by some of the world's finest minds and mathematicians-- the market still fucks them over. How much smarter do you think policy makers are?
Norway has a much smaller and simpler economy (than the US), and is sitting on incredible Natural Resources (and admittedly, has excellent administration over use of said natural resources) relative to their population size. They're like a bigger and more efficient Kuwait. They are a definite outlier when it comes to country economic policy (it's not a pattern adaptable to any country). It is also much simpler to come up with good policy.
When the government is in control of a more complicated system like the US, human stupidity leads to some major fuck-ups. The freer the market, the less effect any 1 party's fuck ups has on the overall economy.
As for the OP I'd say that the "invisible hand" cannot work without a certain degree of regulation. For instance, you can't have a free economy in the midst of civil war-- you need rule of law. "Free trade" cannot exist with rampant monopolization, extortion, blackmail, theft, false information, etc. etc.
Getting the most basic rule of law out of the way, I'd say that defining compliance regulations/practices can be much more difficult than one would expect. Dip your hands in too much and the whole economy comes to a halt. Take the companies too far off the accountant's leesh, and you get . . . well you get the Sub-Prime Crisis (or similar).
If there is one thing economics has figured out though, is that while humans are stupid (or misinformed) on individual cases, they are intelligent in the long run-- which is a whole lot more than we can say about any 1 individual trying to run a country's economic policy.
This is why there is no real "better" solution than to try to limit government intervention as best as possible to eliminating the types of "dirty" or "foul" practices I mentioned in this post, and as much as possible, trusting the invisible hand-- because in the long run, it's far smarter/better than any policy maker.
In general. This is the economy-- there are always unfortunate exceptions.
