Yes, libertarianism is quite close to anarchy or minarchy. It looks like such sentiments are very strong in places where goverment has failed their people for dozens of years, in comparison of Europe for example.
With the exception of anarchism being anti-capitalist.
Any ‘anarchist’ that is pro-capitalism is generally not regarded as anarchist by the wider anarchist movement.
Fun fact: befor the modern US meaning, libertarian used to mean anarchist-communist as a way around french authorities banning the word anarchist in the late 1800 if I remember correctly.
