Infrastructure of independence
It has traditionally been held that collective transportation systems, communal housing etc. is the less wasteful and most efficient form of infrastructure. The more, the merrier. Synergy and large-scale advantages. We are generally assuming that even if communal infrastructure can be difficult to build and get support for, it is more economical, reasonable and environmentally friendly than individual solutions. But this is not necessarily the most attractive way seen from a novosolarian point of view - what we need to build is feeder infrastructures, independent constructions building on existing patterns.
A couple of examples: We could build a bus system running on existing motorways using packet-switching properties, treating individual travelers like IP packets, switching them this way and that according to traffic patterns, some of them optimized according to price, others to travel time. From buses to vans to cars to vans to buses again we could transport people from specific address to specific address in their own time - bridging the taxi system with the bus system. Call this a "SUB".
Another example: Distributing food with the mail system. We have a global transportation system with some latency, but it works. Why don't we use it for distributing food to famine areas?
Basically what we need to do is to use the existing infrastructure better instead of expecting the UN, the US, the EU or some other major agency to build the new ones we need.
Humanity needs independent infrastructures, not ones tied to governments or their derived organizations.
