Sorry to say but this is so utterly useless and only perpetuates the myth that individual consumer choices have the potential to impact the machine. You may do all you suggest and it won't make a dent as the things you're doing or advocating for are simply not in the same "sphere of economic activity". A thing that is sold is already sold (except when a subscription model is chosen). To repair it won't impact those who want to buy the new thing. So you're only taking yourself out of the consumer base.But as it grows nonetheless — or "the billionaires" choose to cater to smaller but high-end consumer groups; or they adapt and conquer the new market niche your interest created at first (see organic food) — your exit won't matter as it is already well compensated for. The suggestion that "think globally, act locally" (i.e., consume locall)y was already a folly in the 1980s. That the "counterculture" is still on this level of strategizing shows how little progress has been made sicne then.

@ajroach42 @ifixcoinops along those lines some groups are running repair cafes https://www.repaircafeusa.org/
