Never said they were equally exploitative, just that we all suffer from some level of economic coercion.

You very strongly implied otherwise:

whatever your opinion of Johns is, it should consistently be applied to anyone who ever buys any product or uses any service.

If we play devil's advocate, the strictest denotation of what you are saying allows for the interpretation that one should consider exploitation in all cases, but you are very clearly implying that there is a comparable magnitude. I don't "apply my opinion of" John Wayne Gacy to someone was convicted of a sexual assault charge, because both people are sex criminals (and should be condemned) but the cases are clearly not comparable beyond a statement as generic as that.

Likewise, I don't "apply my opinion of Johns" to someone who bought a bundle of bananas at a grocery store because both people "contributed in some manner to exploitation" but the scale is not remotely similar and also the latter person still needs to eat!
