Very good observations that come from peeking out of the box. Some things I have considered along these lines. While the farmer grows food for market, I have a garden where I grow food for myself. That produce isn't taxed, like the farmer's is, so all the food I produce, in addition to being more closely regulated by me for dangerous additives or residues, even if not more cost effective than food I can buy from the farmer, doesn't contribute to the parasitic state.

The accountant provides a service that is becoming more obsolete every day, as open source accounting programs enable the doctor to do his own books with the power of multiple accountants doing them by hand. Since the software was not purchased, no transaction incurring tax liability happened, and again the state is deprived of revenue.

It is in this way that decentralization is decreasing the power of institutions. Accounting software is basically a form of AI, and I can see many other ways AI is going to contribute to decreasing costs individuals bear, and the revenue institutions accrue. In each example I gave, the freedom of the individual is increased as well. Is it too farfetched to imagine that by using AI, CRISPR, aquaponics, 3D printing, and a robot surgeon, someday the doctor can be replaced by our own means of production? I don't think so, because health information can be provided by suitable AI. CRISPR can be used to modify organisms to produce necessary compounds that can be grown in our aquaponics setups at home, the compounds extracted, and printed into medicine with our 3D printers. If we need surgery, our robot arms can hack and slash us at home. Given nominal AI and robotics, doctors can be replaced with our own production as well.

While home surgery remains in the realm of sci fi, many, many other goods and services are able to be replaced with our own work today, and development of decentralization continues, so more are coming. Every matter we solve ourselves reduces the power of the state, and keeps our benefit from our work in our personal hands without being parasitized.

Decentralization is freedom, and it's increasing daily.
