Specifically, the government has:

• No right to regulate businesses -- such regulation is an initiation of force when the government drags a so-called violator off to jail because he didn't comply with government mandates.
• No right to levy general taxes -- taxation, if done at all, should be specifically charged to those who use government services on a per-use basis.
• No right to mandate minimum wages -- it is an initiation of force to physically prevent a worker who is only skilled enough to earn below the "minimum wage" to instead have no means of legally acquiring a job. Further, like all forms of price control, minimum wage laws necessarily create scarcity (= unemployment). Remember supply and demand graphs? Minimum wage laws are a gun that says, you may not meet at the intersection of supply and demand. It puts marginal employers out of business and marginal employees out of work. No government law magically makes an employee's labor worth more than he really is. Reality is absolute.
• No right to regulate who can work at certain jobs by issuing licenses -- such licenses are an abuse lobbied for by unions and workers who want to raise the barrier of entry in their field. It is an initiation of force against those who want to work in that field and those who want to pay the market price for such services, rather than the artificially inflated rates due to high barrier to entry.
• No right to determine which buildings can be built where -- general zoning regulations is definitely an initiation of force. It violates the very basis of property rights: that a person can use his property however he sees fit. "Zoning" says that no one really owns property, they just hold it by permission of government and use it by permission government. This is called Fascism, in case anyone forgot. Property is a right, not a privilege.

Many socialists (e.g. Democrats) assert that "freedom" means freedom from economic oppression. By that they mean that if another person has more than you, then you are clearly being oppressed, and it is up to the government to forcefully take money away from the rich and "redistribute it" to the poor. This manifests itself mainly in graduated income taxes and entitlements. The main flawed premise behind this demented way of thought is the premise that wealth is a zero sum gain -- that one person's affluence means that others must be poorer as a result. This is false. Wealth is created. It is the product of the mind and hard work. If one man creates more through his efforts it in no way detrimentally harms another. In fact it's the opposite. When one man becomes more productive, he can buy more from other producers, helping to lower prices for everyone due to economies of scale.

It is only fair and just for each person to keep what he earns. It is barbaric to penalize the successful for being successful and reward the failures for being failures. It is not government's role to provide a safety net. "Falling through the cracks" is not to have one's rights violated. Safety nets are for charities and individuals to provide if and when such a net is deserved; not for the government to provide for anyone who wants it regardless of merit or circumstance. Help regardless of desert is a terrible injustice and an incentive to fail.
