Individual action does not change the ultimate outcome. Protesting capitalism through the way you consume or the amount you consume does nothing on the individual level. There is no harm to it and should you wish to live that way I'd encourage it certainly but this methodology is short sighted. If it were a large collective movement aimed to reduce corporate profits it might accomplish... Something but it probably wouldn't be much more than making some rich people angry and they might suggest the government subsidize them or do something to encourage consumerism or they might withhold investments to further crash the economy. That's only if we try really hard though and I don't think that could ever happen on any large scale.

Currently efforts in the imperial core are best used in teaching people and organizing with your local party. volunteer work and unionizations are much more beneficial to your community long term.
