I take it your definition of communism is then "that what lets land and life die"

Communism is normally defined as: "all production of value has to be done by a central authority" ; well, normally, it is limited to "all means of production (capital and land), and all income obtained by that means of production, have to belong to a central authority, who will remunerate labour in an egalitarian way so that labourers can buy said production".

I'm talking about something entirely different.  There is no central authority, but if you want a clean street, you should start cleaning in front of your house *because we're not going to outsource cleaning*.  The only thing that is needed is that stake holders run a node on an old PC.  If you're not willing to put in *that* effort in order to save the system, well you can take the risk that your neighbour will do it for you ; but you shouldn't complain that your system dies.

There's nothing wrong with such a system dying, that's my whole point.  A token doesn't have to keep value.  It needs to have sufficient value between the moment I obtain it against a sale of goods/services and the moment of spending to obtain goods/services.   Then the token helped me create economic value by exchanging goods and services.  If a week after that, the token has no value any more, I don't care.  Token systems are ideally like Kleenex.  While you use them, they are valuable ; afterwards, you throw them away.  Of course, it would be useful that the Kleenex lasts a while, because it takes time for it to acquire some acquaintance in the circles where it can/will be used as intermediate asset.  And a good token system will last long.
