Governments have the legal right to use force against individuals. Individuals, and individuals that band together into organizations, have no such right.
First, there aren't many large scale bands of individuals that don't also obtain special privileges from the government (aka incorporating).
Second, while these organizations theoretically "have no such right", there are plenty of instances where they do directly wield force yet escape justice, abuse the force-wielding functions of government to harm people, or use their concentrated power to buy off parts of the government (principle agent problem). Insisting that these are ultimately government problems because a perfect minimalist government would not succumb is highly wishful thinking. It's falling into the classic political trap of addressing one half the problem while drumming up full-speed-ahead support for the other half.
It's rather difficult to defend yourself against an organization that can use it's wealth and influence to leverage the government to make it a crime to fight against them, or to make it so expensive to compete that unless you're already rich you cannot, or to sick FBI or police or military on you.
A company would not be nearly so dangerous if it could not in turn influence the government to destroy you. It is much cheaper to give campaign donations to a US senator and then hand him laws to pass or ask for subsidies or for no-bid government contracts than is it to actually compete in an open market where you have to provide a better service for a better price than everyone else.
I find it amazing that people clamor for the government to protect them and yet day after day we see examples of the government crushing the helpless, confiscating their property, throwing flash bangs at their children, torturing them, or just straight up murdering them, and all without consequence, at most you get a pretty speech than it s back to business as usual handing out billions of tax payer wealth so companies can give some of drippings back to our 'elected' representatives.
And when you bring this up, what do people say? They tell you it's just bad luck, there really are some good people in government, try contacting your your congress critter, try getting into public office. The definition of insanity is to repeat the same action over and over again and expect a different result.
Both of which rely on and aggressively use (via bribes) the government's legal right to use force against individuals as their means to implement their policies.
