By never bestowing govt. with the ability to influence the market in any way, thus removing any market incentive to lobby govt.
At that point, wouldn't there be a market incentive to CREATE a government favorable to their means?
Not sure this is a legitimate example, but isn't it in the HMOS' favor to support a program like Obamacare as it gives the govt. power to funnel the money to them instead of supporting true laissez-faire which would open the market to more numerous and diverse competition? Don't Raytheon, Boeing, et al. have a vested interest in supporting a government large enough to need their weaponry?
Also, does a government too weak to influence the economy in any way have the strength to fulfill it's constitutional obligations [speaking specifically about America here]? Just by providing legal tender and creating money, doesn't the government affect the economy?
