I think that would work, too, however, with legislation they can always get a friendly court to rule against the law. Whereas an amendment would be unassailable. The problem with an amendment is getting it through the process, which is hard to foresee. Freedom of association is one of the fundamental human rights that is a natural human right, like property rights. Theoretically, we don’t need a law to have that right, but the state being the state, they limit every right they can.

Your basic Libertarian logic is tragically flawed and I have already explained why. You have swallowed flawed and simplistic dogma hook line and sinker and thus cannot respond to let alone credibly refute the points I have raised many times already. Yes, in general price controls will tend to distort markets and lead to an corresponding increase or decrease in demand or supply. But in the specific case of wages and especially the wages of low income earners, there is a considerable and well evidenced logic and phenomenon showing that increased minimum wages drive increased demand across a wide range of goods and services- because low income earners spend the vast majority, if not all of their incomes.

So the increased consumption of goods and services that an increased minimum wage results in leads to increased demand for those goods and services, increased demand for workers to be employed in the supply of those goods and services and therefore an increased employment and increased overall level of economic performance and well being, not only for the lowest paid but for many including employers who provide goods and services to the least well off members of the economy and society.

Wealthy luxury goods and services providers may not enjoy such bounty but the least well off and those who provide them with goods and services will thrive. That is imo a desirable result. Lack of minimum wage will lead to the opposite result of greater inequality- this is seen in the most corrupt and depressing regimes and nations of the world - high levels of inequality result is huge wastage of human capital, chronic poverty, desperation and spoilage of human potential (for example think of the inequality of education opportunities between wealthy and impoverished families) and a small elite of fat greedy parasitic overlords who usually also capture the political process to perpetuate their rentseeking greed.

In addition the inherently relatively weak position of low income workers in relation to employers in terms of negotiation will where no minimum wage is set result in wage slavery and those workers living lives of abject and debilitating poverty. There are many many examples of this throughout history and in the current day- as I have asked several times- Where in the real world is there no minimum wage but a healthy functional economy?

I have made these points many times already and now elaborated upon them further- you have failed every time to address let alone refute them...instead you return time and again to repeat your simplistic Miserian dogma that allows no exceptions and paints an illusory world of black and white but flawed logic- it does not and cannot address the facts and issues I have raised...which factor in the complexities, quirks and uniqueness of human nature, and political and economic realities.
