Trading with external source would be the same, but say if you needed to order a part for something and you didn't have enough money, the community would try to support you
The focus of "but whats in it for me?" will be steered towards "you need it more than I do" so trading internally will be more of giving away resources or labor as a favor knowing that you'll be treated the same later
Essentials are taken care of: food, water, health and energy.
No more Debt or use of credit
Lack of greed or glutenous purchasing of unneeded items
2) No corporations or restricted job positions
No more unnecessary jobs that you are stuck in due to the need for money and lack of "education" or the job you want is taken.
No more corporate regulation or control
No high up luxurious CEO like positions that get paid more than they need
No worry about losing or obtaining a job to get by
No unnecessary research and development of a product thats harmful or cheap just so it'll work better or sell more
3) No internal business
Lack of Consumerism
Possibly of "open shops" that people "sell" their creations for free
4) No government controlled schools
No unnecessary classes or lack of wanted classes
No controlled curriculum for teachers that dictate what they teach
The ability learn more, faster, and as need and wanted
5) No medicare or traditional health care
Lack of health problems
No more worrying about if you'll be treated or covered
No more Government crutch
No harmful Pharmaceuticals or worry of others "pill popping"
6) More Community involvement
The ability to have regular gatherings and events with everyone due to the fact that no one has to work or go to school
7) Better Community support
As the community grows there'll be more to help with the new comers house, more diversity in talent and knowledge.
When someone is in need, there will be more opportunity in a small community to seek and find help
What a starting community will look like
Starting with small Cob-based houses that are round in order to hold pressure. They'll be about 30 feet in diameter giving you 700sqft of living area. The house will have a small dive chamber as an entry to pressure up and down to enter the house. This could be later connected to other houses and greenhouses.
Homes will gradually start gaining tech with energy sources first. That could be basic solar made at home to HHO tech with a gas generator. Water would be welled and rain would be collected and stored. Food would soon only come from the greenhouse.
As the basic needs are met, more and more tech will follow. Foundries and forges for melting and working metal. 3D printers, laser cutters and CNC mills would be for home manufacturing for endless uses. Micro-controllers including Arduino would be used for security, weather monitoring, automation, etc.
Simple yet more advanced idea for a house and greenhouse in one
What the end result to a fully functional and self-sufficient community will look like
I'm planning to start multiple "villages" though out the world. These will consist of 100-10,000 people. The idea is to only have people together that want to be together, so that theres less conflict and more opportunities to grow and learn.
These Hyperbaric living conditions can consist dozens of small houses and green house on the surface all connected underground with the mass majority of room underground. This would have minimal impact on excessive unsightly buildings that eat up beautiful landscape and wild animal's homes.
The other bigger option is the best of both worlds. This would be cylindrical "domes" that would look like a massive green house that would incorporate the landscape that would allow even more beautiful living area outdoors by having luscious gardens, trees, and fields. The same would go for here, most of the square footage or buildings would be under ground. As for the greenhouses for food, they would have their own smaller and similar building outside of the main one or possible be underground with controlled lighting.
An entire town will exist without a clue from anyone flying over. The town will contain advanced medical facilities that are adapted to the new needs or lack-there-of of the people. Entertainment halls for anything and everything. Studios for all arts. Labs for all sciences.
The tech that will reside here are incomprehensible do to the lack of restriction and mental and physical health of the people. Some of this tech will include new or reinvented transportation like Inertial Propulsion that can take you to the Moon in 30mins or Mars in 1.5 - 3 days or anywhere on the planet within half an hour.
With virtually unlimited energy at you finger tips, what would otherwise be too costly or inefficient can now be used no problem.
More importantly will be the focus on learning and teaching. Having the ability to do so much more hands-on learning and entire museum-like educational centers for all ages.
