This page provides some indication of a what a new state might be like:
In terms of humanity:
It is suggested that the new state be a vision for the future - allowing residents to break with the destructive and damaging practices and developments of the past - instead allowing people to exist in a society where they are valued as people, and NOT just based on what they can do (i.e NOT just based on what markets think is important) and also not valued on how wealthy they are (unless you are thinking of wealth in terms of the love, compassion and care of which they are capable - which is the likely currency of the future).
In terms of living styles and economy:
We need to wean ourselves off fossil-fuel and the related coercion and wars that are conducted to control and extract these. Thus much more local production (and local jobs too). The most productive farms are small farms, and it is likely that many people and families - if given the resources and opportunity - would be able to produce food for themselves and others, and possibly other materials (see 3000acres.org for a project in Melbourne and solefoodfarms.com for one in Canada). Of course, many people will choose to remain in the professions and it is expected that in this regard even more employment options will be available on the Peninsula.
(See photos here of Northcote Resident Angelo Eliades' backyard food forest. This produces over 200 kilograms of vegetables each year from 80 sqm of garden beds. That is 6 times more productive than commercial wheat growers.)
I imagine that many houses will be surrounded by food gardens (either individual or shared) and local communities may also have parks that are planted up as gardens or food forests. Houses may be much like the Russian Dacha's shown below:
It is quite likely that car use will be reduced. In part this is a necessity, but in much larger part, this is likely to be because they are simply not needed most times. With localised communities and shops, schools and work etc all in close proximity in a beautiful garden setting (not ugly wide roads and dangerous traffic) with an active community where everyone knows nearly everyone else - why would you not walk? OR at least use public transport - which could be seriously ramped up if many of us devote some of our car budget towards public transport (think - no flat batteries, no expensive fuel costs, no expensive repairs and repayments, no huge taxes for expensive roads - that is freedom!). It is proposed that car pools be arranged that people can contribute to so as to get access to cars cheaply when they do need them.
It is well known to many scientists that a good diet of properly grown food (in living soil - not dead soil with chemicals added) will lead to almost perfect health (see for example the research of Sir Albert Howard and also the experience of the Hunza people). Add to this the much cleaner air and environment due to no car and truck emissions (all very dangerous) and less industrial chemicals etc in the environment, and people's health should improve dramatically. This will reduce the drain on the public purse giving people more time and money for other activities.
In fact overall, I would suspect people would have much more time for family and community, many more opportunities to spend time with others (and care for and about them) and be substantially less stressed. With all the cost savings of a localised economy there should be a lot more resources to help those in need -either by private people (given the free time and wealth of everyone) or the state (due to lower expenses).
