Maybe you should give the article a read then? It is saying exactly that, that individual actions and consumer activism don’t do shit and structural changes are needed. It even gives some examples for structural changes that could be helpful in the short-term.

I added this anecdote just because I was surprised at the scale that Amazon had an impact on the economy. And yes, it obviously didn’t do much when I took individual action and boycotted them (apart from giving me a feeling of some integrity).
