Here's an idea: invest in "free market solutions" to the statist forces. If the pure free market is such a wonderful thing, how come it can't provide you with any protection from statist forces?
"Protection" is a pretty broad term, which makes it harder to answer your question. Security is defined in terms of a specific threat model. PGP makes you "secure" against (most) unauthorized reading of your email messages, but it doesn't secure you in any way against muggers with guns.
There
are lots of free-market services out there to protect people from the state. Defense attorneys can secure you against false accusations, luckily for the Duke lacrosse players. Audit defense services protect against IRS harrassment--and cheaply, too. The National Audit Defense Network tried to charge $600/yr for the service, but you can now buy audit defense per-return through TurboTax for about $30.
If you include the black market in the "free market," then various sorts of protection can be had there, such as off-shore bank accounts, money laundering, goods prohibited by the state, etc.
But what you probably mean is, "Why can't the free market provide guaranteed protection against the US army and Federal, state and local police forces?" Your question could be refer to individuals like the Browns, or to foreign nations. I'll stipulate up front that the free market
doesn't offer protection against a division of American infantry, or a squadron of fighter planes, or a nuclear-tipped cruise missile.
The tactical answer to your question is simply that lovers of freedom are outnumbered. One million lovers of liberty (to pull a number from the air) can't hope to fight off 300 million slaves. Freedom is
morally superior, but it doesn't confer a 300-to-one
tactical advantage. In addition, the side that's willing to maim, kill, slaughter and enslave has a
tactical advantage over the side that refuses to do those things. The state can and does wage preemptive war on free men, using gun control laws and all sorts of other immoral means.
Most libertarians have no intention of waging war for freedom. They believe that their fellow man really does love liberty, but is confused by habit, history and propaganda. They believe that liberty can and will defeat the state by converting a majority of mankind to liberty. From their perspective, liberty
can defeat the state; it just hasn't yet because we're early in the game. I don't think we should scoff at that, at least not if we can easily swallow the claim that we're "winning" in Iraq despite how hideous the current situation there is.
