Fair point, however the link between systemic and individual changes is not as binary as it may seem, it's long debated thing, but in a nutshell it's essentially a circular problem. Lot of permacomputing participants are involved into activist work and encourage coop forms of organization, collective action, creation/joining of unions, and make use of their technical skills to help less privileged groups (some of these encouragements are also listed in the principles). All of these things have impact on the perception of mainstream politics, capacity for change and how electoral politics could be activated. Maybe this could be made more explicit.
