It's fun to think about, but states grow themselves. It's their thing.
Even if you achieved this, it'd be a twisted, vicious counterfeit version inside 10 years.
We can organise to do important things without attacking and threatening each other.
When you plant that seed, that it's occasionally justified at a very small level, the eventual garden full of weeds is inevitable.
Remember, everyone thinks they're a minarchist.
They just want the state to do the few things they consider important.
I agree on the fundamental issues, but still the Government has te be shrinked somehow. You can't make it go away overnight, that will result in total chaos.
But with a decent taxation system and a really informed population that does strive for liberty and personal responsibility.
Then over a couple decades the Government can be pushed back into a minimal size, perhaps to zero.
But it can't happen instantly.
