No, capitalism is not the absence of regulation, that is nonsense. Capitalism is targeted regulation for the purposes of allowing the principles of capital-ism to flourish according to their own nature. Capitalism is meritocracy in a field of enforced equality of opportunities such that the use of force to destabilize and overpower higher-order merits is banned (some dude cannot simply stab you and take your money when you made a contract or economic transaction with him, for example). Without law and order, economy is impossible, so are human rights impossible. Capitalism requires basic legal regulations against theft and fraud, and requires a courts and police system to enforce that law.
Anarchy (absence of all regulation, of any laws) is not capitalism but the absence of capitalism, indeed the absence of civilization as such. Socialism (extreme regulation that destroys capitalism and culture) is far closer to anarchy than capitalism is close to either socialism or anarchy.
Whoever thought up the relation between anarchy and capitalism was a useless worm. A pathetic will to nothingness whose nihilism and personal weakness and cowardice ruled his desires to strip everything away from everyone, so that “equality” could reign as gross inequality. “We are all equally savages in the wild”, that is the dream of the absurd anarcho-capitalist.
Laws that protect rational human rights and that limit government to its proper functions are good laws. Laws that go beyond that are not good laws, and are indeed a slippery slope into socialism. Socialism is when the state usurps and owns the individual. The trick is not to have no state but to have a wisely limited state; you cannot get around the necessity of law. It is simply those whose ressentiment in having no power in law has taken over that you find this anarchist urge.
