I'm happy with Amazon, if you don't like them then don't use them, but don't punish us all with going back to the shitty local commerce.
It's not like online retailers don't exist. Well, for now. They _will_ go under if we just let Amazon run everything unchecked.
What matters is that we provide an environment within which we can trade amongst each other as (relative) equals, not one in which the Great Overlord owns all of the means of production.
This isn't a border dispute, this is about behaviour within a country.
Forcing the adoption of exploitative labor practices is helpful to consumers within that jurisdiction?
