That's always been the opinion of the authoritarian.
Perhaps because you perceive coercion as necessary?
I'll ignore the circular argument you're presenting, and ask you this. Why do you think people would cooperate as a whole if left to their own devices?
Why do you think a monopoly on force can instill virtue?
People, for the most part, respect property of others and trade freely. In the pursuit of profit they provide others with goods and services that they need. People cooperate and trade peacefully every day for mutual benefit, do you not see this? If you have a job and buy things, you're "cooperating". All the state does is interfere with and restrict voluntary trade with violence. If humans can't cooperate, then how can a government work?
It's not circular reasoning: You believe that coercion is necessary, therefore, to complement this belief you must also believe that cooperation is incompatible with human nature. He's saying the causality is backwards.
So what of all the scammers, especially here?
Yep, better give a monopoly on violence to an institution called government to steal everyones money to pay for protection against scammers.
What about the scammers in parliament, to whom we have given all the guns?
Just because we don't have a state initiating force against peaceful citizens doesn't mean we can't have protection services and defend our property. non sequitur. Besides, is the state protecting you from these scammers now? no.
If that is the case where are the protection services that get your bitcoins back from scammers ?
Nonexistent, because bitcoins are your touted unregulated currency. The very reason you love them so much is why they are so easy to simply steal.
