Daily politics, anything shorter than a several decade long trend or a revolution will simply not affect you and is a waste of cognitive resources and often a source of frustration.

AFAICT, this is simply wrong. There are many political trends (on a scale of several months to a few years) which will noticeably affect the typical person. This is not to say that affecting such trends is easy or that conventional "political involvement" is useful. But this should be regarded as an open problem, not as a reason to renounce and surrender any kind of involvement with these issues.
