A consumption strike is still a strike, and honestly could be more effective than a traditional strike.
The US economy is essentially completely reliant on consumption at this point, it's the place where we have the most leverage.
It's also very easy for an authoritarian regime that is inbound by law to retaliate against traditional strikers. It's much harder to force us to consume.
It also doesn't have to be zero consumption, by loca, but used, use cash, barter, and trade.
