That’s always been the argument for those who want to exploit workers
I think we're conflating business, generally, with capitalism. There are important distinctions. Some policies, like minimum wages,
affect all businesses, but most do not. As noted earlier, taxes don't
regulate businesses, they are simply part of the environment in which the business operates - like roads, power, labor market, supply sources and competition. Minimum wages are like that, too. Not all regulation is "of capitalism". Is it "
commerce" that is being regulated, or merely the environment in which the commerce is operating that is being regulated?
(Strictly speaking, mom-and-pop businesses and self-employed entrepreneurs are not "capitalists". Capitalism implies a corporate form, where labor and ownership are segregated. In some respects, once a business is large enough to hire labor, it becomes "capitalistic", because that labor is no longer connected to the capital of the business. But, I think it is important to define terms, rather than splitting hairs.)
When government regulates an activity, say oil drilling, it creates rules that are specific to that activity. The more that activity has external impacts unrelated to the actual activity (extracting oil), the more regulation, indeed need for regulation, exists. There are very few regulations that apply to normal business
transactions (I sell you a widget for x dollars, price negotiable). There may, however, be a lot of regulations that apply to other business
activities.
More, later, I have life activities to attend to.
