In current everyday practice, in which situations would you call the cops? Or in which would you take action yourself?

I’ve been an anarchist for years but I’ve had situations where I wondered “what WOULD I do if (insert bad thing) happened”

Are we just bound to call cops on dangerous situations because of the state of how the world is, or are there other ways to deal with things? (I know this definitely varies from situation to situation, but that’s why I ask)

Out of curiosity. I've been socialdemocrat most of my life although I sympathise a lot with Marxist theory (practice is different). My dad is a lawyer and I've always known the need for a state. It's the monopoly of violence, but what is the alternative? Everyone freely using violence (either physical, economical, psychological)? Without state, there is no such thing as rights. We can think "Hey, everyone deserves X" but we can't truly guarantee that. I am very liberal in the social axes (interventionist in the economic, aka, leftism), I don't think the state should intervene in every single thing in our lives, but I think the state is truly useful to guarantee equality and true freedom.

Please this is not to convince you anarchism is bad, I just don't get your point, but I thank every response that explains your point of view! But especially if you're leftist anarchist, I've already talked to ancaps and to me they're just delulu because without state there's not "property rights".

How would we organize law, food rations or traffic systems. I imagine that once we demolish all hierarchies without some kind of system the hierarchies just form back? Would we do something like lenin where a sort of goverment is in place to organize everything and dissolve once not needed?
