An example of decentralized means of production are guerrilla gardens, such as I have growing innawoods. If I am prevented entry to grocery stores, I will still have access to those gardens, creating independent means of supplying my needs.
Any means of producing a good or service you can control yourself is decentralized. Your ability to secure your home is critical to your ability to have personal means of production in your home. Security is the hurdle you must surmount to possess means of production, and therefore the most important aspect of decentralization you can adopt.
You have discussed your desire to live nomadically, and the ability to provide goods and services in such conditions is limited by the need for mobility. I recognize that living in an apartment in a city is practically impossible to secure from armed assault, and this is a significant recommendation of nomadic habit.
Securing our freedom will not be easy. We each must manage our personal security and our success as individuals concatenates with that of our peers to produce free society. Your personal circumstances depend on you, and cannot be provided for you, or prescribed from a list. Your decisions are the source of your actions, not my preferences.
What you ensure will be available to you, in terms of goods and services, will be available to you, but more than that I cannot be sure you will have available. Therefore I have recommended undertaking means of personally producing goods and services necessary to you. That is exactly the definition of decentralized means of production I use.
A 3d printer you own and can keep is a decentralized means of production of widgets. A garden that is productive and you can access is decentralized means of production. A grocery store you can be excluded from, or a hardware store you cannot buy widgets from is not decentralized means of production.
That is what I mean.
I don't even have a home atm..
and I don't think I would find good "uncultivated" spots which are also a bit hidden for guerilla growing.. I'm from germany.. and everything is overcultivated (and forests dying cuz of it - monocultures everywhere)
I also think one needs to be kinda static (to have a secure home) and simultaneously mobile (to get to all those different ninja grow spots).. while I have my oldtimer enduro, I'm not allowed to drive it cuz I had used cannabis against my permanent pain
but yeah, I'm on your page and am really thinking hard to plan my way..
I'm not even sure anymore if I still want to get educated for a job in germany (you have to cuz of all those regulations), while I prefer learning autodidactic/ teaching myself.. but yeah there is a war against decentralized people like us
Physics is the ultimate arbiter of what works better than other things. Decentralization works better.
Adopting means of production you can use yourself will be better than dedicating your production to overlords that then provide the goods you need, maybe. History reveals that overlords have destroyed peoples' gardens and starved them to death in the Holodomor, Mao's great leap forward, and Stalin's purges, amongst other horrific atrocities.
It is necessary to undertake independent means independently, and cryptically.
We do not undertake to keep our access to videogames or beer, but the necessities of life itself, and the blessings of civilization. It's not going to be easy. It's probably going to be called a crime.
Do it anyway, and live.
