On the other hand, it's harder to make a sentence flow around "oligopolistic".

I feel like seeing that Amazon owned a third of US ecommerce, before the pandemic stomped brick-and-mortar flat, goes more to my point than to yours.

Sure I can! You're quibbling over my choice of a single, admittedly inexact but contextually plain, word, rather than engage at all with the actual point I made. I'm just trying to meet you where you are.

> a single, admittedly inexact but contextually plain, word

Within the context of a policy discussion, a monopoly versus oligopoly is a pretty material difference. Every growing business at some level “wants” to monopolise their niche.

You are still not addressing the point despite wording clarifications that addressed your original quibbles.

You're responding to someone else now.

I'll quote myself:

> I don't really have much to disagree with you about, but maybe you want to check the "monopoly" claim.

If you want to have a debate, we can. Name something you want to disagree on.
