Can we truly have a fully decentralized system? For example, we control our own money, properties, internet etc. If we can, how can we achieve this and what obstacles can we face? I want to control my money and I don't want my government to control what I see on the internet. There are ways of overcoming some of these but the whole internet is coming from the ISPs. We may have a satellite(Elon Musk) for internet which makes the decentralization easier for us.
A fully decentralized world cannot exist for a long time. Humanity in its development has gone through this more than once. Therefore, there is a saying that one who does not want to feed his army will be forced to feed someone else's. Decentralization in public life means complete anarchy. How then can you control your property, your money, if any group of armed people can enter your house and take away any property, including your cryptocurrency computer? Are you going to hire your own private army for this?
The government, the army, the police are still necessary, as are certain rules of conduct in society.
Stealing things from people who live in decentralized world will be made difficult.
There will be stuff like alarms, Cameras will be watching, there will be very tough defenses, and quick means of escape (known to only the citizens) . Things will be reordered frequently to make detecting this security secrets very difficult.
Besides, having too much physical properties will be discouraged amongst the citizens. The properties should be easy to move around and easy to decoupled..
Much of our wealth will be in decentralized world, so that they can't be easily stolen. Decentralized Insurances will also help incase of theft or accidents
