There's no "should" because there's no high authority in humanity which decides what should and shouldn't exist. Banks exist because some people want to found banks and then other people want to use their services. The only way to prevent this from happening is to threaten violence or threat of violence to either of these people.

The better question would be, why would anyone use violence to force his opinion on other people.

That's not quite true. Take a look a the various narrow banks which have been founded and people want to use their services, but the government won't approve them to operate.

That's a weird view.

We could also just, you know, vote away banks. I'm not sure why a centralized bank would result in violence.

How are laws and the will of the people enforced? Typically via fines or jail time... both of which are backed by violence.

The enforcement of this vote (or law) would be violence against others. Majoritarian tyranny is still just tyranny.

OP is making a dumb libertarian argument basically saying "there's nothing stopping people from doing what they want except the threat of force/violence" (which is trivially true, and the mechanism by which any group of people - even democratic societies - imposes their will on insiders or outsiders), and "do you really want to use THE THREAT OF VIOLENCE to prevent me from STARTING A BANK???" as if it's different from the enforcement of any law. OP questions the use of "should" uncharitably, because the original comment's unstated assumption is clear - society "should" be set up to tradeoff freedom and minimizing collective harm. Violence is not the only form of harm; unregulated banking can obviously cause harm in the society (starvation was pretty harmful in the US during the Great Depression), and so it's valid to question whether or not society should consider how the benefits of private banking (with any amount of regulation) trade off with a public alternative.

The answer to that question, is the very same reason you gave for why banks exist.
