What exactly is meant by letting the system fall apart? The economy is the system that keeps you fed. You as in yourself. As in your family. As in your friends. As in the people who live near you who will also be driven to desperation. As the solutions you pondered had intended, we have to minimize the human cost of fixing our problems -- as we are those humans.
Authorities don't like to be challenged. They don't like their rules to be questioned. They don't like people to make their own "right of exit". To them, not following the "rules of society" is a threat.
If you understood that, than you see that I don't see the government as a vital machinery of some sort. It exists by force. It's the modus operandi of all governments.
All the solutions that I proposed is exactly opposite of that. My first solution is counter-economic on a purely voluntary scale. Seasteading moving to a location where you won't be harassed by authorities. It's non-violent, and non-coercive.
That's an ideology in itself.
But I do not expect governments to sit idle. They will certainly will not approve of a voluntary charter city created by libertarians. They did it in the past and will do it again.
Think of Snow Crash. In there, they have various enclaves and franchise area such as "Mr. Lee's Greater Hong Kong". But the US government itself is rotting away. Inside, jobs are mere make-works. They have surrendered much of their terrority to various entities and corporations. Then they just get ignored by everybody.
I want them to make ineffective government systems irrelevant, or at least co-existing, and competing. I want a world where rules are being optimized, instead of become a source of corruption.
Then, we can finally escape the dangerous race of technology versus government decay. Either technologies elevate us to singularity status, or the government causing systemic collapse and we're back where we started, or worse, nuclear annihilation.
Well, I'd kind of agree with that last part .... it's race.
But keep in mind that what we have to do is navigate the very dangerous in-between-times that are coming ... keep in mind that novels can make the process of decay and collapse seem OK. The reality can much more horrific. Ever research the things that happened at the end of WWII. Whole nations (Poland, say) uproot and moved, with a fair portion of the people DEAD as a result. The end of the Roman empire wasn't pretty and people much less dependent on really large scale structures like food distribution networks then (food ... survival, as gp said).
I mean, unlike in a novel, the US government has not become less controlling as it has become more corrupt. Just the opposite...
