this video explains it well

Notice how ancaps haven't done anything? That's probably because its a stupid ideology.

As I explained, private ownership of property itself is a state. Non-violent anything doesn't exist, that's stupid. All it would take is a single person to kill every pacifist in existence if nobody used violence to protect them. Again, the rich right now already have nothing against bombing children using white phosphorous and genocide for profit, you really think the lack of a government would change that? That's as delusional as you can be.

Capitalism rewards greed. Capitalism rewards underhanded and violent tactics for more profit. Capitalism rewards death, starvation, and slavery. Capitalism must be destroyed for the worker to be free. Capitalism must be destroyed for the world to be anarchist.

To top is off I will quote the slogan of the first self-proclaimed anarchist: "Property is theft". Although future anarchists have followed up saying that's wrong. They said property doesn't objectively exist and thus can not be theft. It is simply a state. Taxes are rent. Wages are wages and Property is Slavery
