We would never know that until people are allowed to decide for themselves how they want to protect themselves. Right now we have two problems: 1) we are forced to allocate huge amounts of money for various "protection" of dubious quality, so we don't have much money left for extra protection that we ourselves may choose; 2) various business models that might explore alternative ways to protect people are either prohibited or kept away from existing monopoly markets protected by the state.
In short: while there are state guns, we cannot know if they do us any good. And I very much suspect that any person who constantly coerces you "for your own good" without a good proof is always an evil sadist. (Parents may force children to take a medicine because they can then demonstrate that it was actually helping. Like you may drag me by force from under a running bus and then tell me why you did it. But constant abuse without a proof and religious brainwashing is pure sadism.)
Today, people will still put their money on companies that return a result from that query.
That is, most of the MLM companies
The problem is that they force C, D, E, F and many others to pay for it. If I don't think the government methods really help anyone, or at least me, I'm still forced to give a part of my income. Also: didn't you notice that almost any voluntary service or product costs the same for both rich and poor, while compulsory government services are somehow priced in a portion of your wealth? Don't you feel that you are being abused?
Get a grip. We all benefit from the collective services, and we give in proportion to our ability to do so. If all were asked to pay the same price then the poorest would have nothing left for food.
Policemen do not pay taxes from their salary (even if formally they do). They are net tax receivers. And they also get to hold a gun to your head when you do not give them money, or refuse to pay it from your employee's payroll, or something else (as I said, the paperwork is huge and complex to hide where exactly the gun is being pointed).
When you are being robbed and then given some bribe to make an illusion of a good done to you, it's not a "service", it's a bullshit of a catholic caliber.
As I mentioned many times again on HN, pro-government or pro-law rhetoric is no different from religious bullshit that one group of people uses on another group of people at the expense of someone else.
Compare:
"Without religion and church there's no morality" => "without government we'll have anarchic chaos"
"You must trust pope because he's set here by God" => "You must trust mr. president because there is society that elected him"
"If god does not exist, who created everything?" => "Without government how would we build roads and fly to the moon?"
"The Bible says what's good and what's bad" => "The constitution defines our rights."
"If you are against religion, you are against morality" => "If you are against government, you are against society".
