if the question read "do you consider the choices you make as prefigurative?" (and then defining "prefigurative", which this spellchecker underlines red...."choices" might need more definition too, but i assume it relates to choices of buying or not buying), then i'd give a crack at an answer.
Based on what I understand you to be asking, I would say that most people make a differentiation between consumer choice and prefigurative politics, though there is perhaps some overlap. Choosing to limit one's entanglement with capitalism is sort of about making do in the here and now, whereas at least as I would use the term prefigurative politics might be more like building in ways that is "building a new world in the shell of the old."Here might be the differences as I see them:
Does this sort of clarify how I would think of the difference? I can provide some more concrete examples of some of these in comments if that seems helpful.
