1. Food - Seeds: of course they are not unlimited, however they depend to a great extent on other resources – just as information is reproduced depending on other resources (hardware and human). The reproducibility of seeds (and the recombination thereafter) is therefore indefinite – there is no limit to how much can be done with them.2. Shelter - Couchsurfing etc. Less and less houses and more mobility - shelter communism will require rethinking nuclear families living in an enclosed space and all that this entails. People could visit and do jobs with machines and hardware.
3. Tools - freecycling. There is just too much stuff, that can be recombined in different ways and the recombination can be made available to all (it's information).
