But that's not what the parent comment is talking about. Sure it's great to have every product listed on Amazon, however, only select sellers (based on certain metrics) should be able to sell those products.
Okay, but who's going to pay for that sort of thing? Ultimately it'd mean higher prices, and since sellers already face a burden of (iirc) ~$3/unit plus shipping to FCs for Amazon to handle shipping/returns, people will just buy from eBay at that point.
Also, it would lead to more stories like the other one that was popular today, along the lines of "Amazon Shut Down my Store for No Good Reason".
Higher prices are fine if it stops buyers spending money on worthless filler products that either work poorly or don't work at all.
Your comment demonstrates why price-driven as opposed to value-driven economics are essentially irrational.
"I want to pay as little as possible" turns out to have all kinds of unpleasant outcomes, not least of which is the complete collapse in quality in certain sectors on Amazon.
