I have zero trust in anything decentralized in relation to money. Would definitely like a central authority to complain to when someone scams me. Implementing it like lemmy would make it impossible to effectively ban scammers and would also make searching for stuff annoying as hell. I already hate how annoying it is to search for things on different instances for this stuff.
Wouldn’t that just be ebay? Or ebay before they began expanding? In most instances nowadays you can buy direct from manufacturer as well, and that’s becoming more common as time passes and companies invest in their own distribution infrastructure
That’s still centralized the same way that Amazon is, they just don’t use the same aggressive affiliate program.
A federated marketplace would be like if you could go to one portal and see posts from Target, eBay, craigslist, and Etsy all side by side, and the user could control their search and ranking algorithm instead of the marketplace selling the top spots. I would like that a lot.
