It would be "the Chinese will sell you anything" if they bought it on Alibaba and imported it on their own.

If you buy it on Amazon, it's "the Americans will sell you anything". If Amazon is too lazy to do due diligence on their third-party sellers, the blame should fall on Amazon if the item turns out to be illegal or dangerous.

Amazon chose to make direct fulfilment almost indistinguishable from third-party fulfilment. Don't want to be treated like a regular store? Then don't make your marketplace behave exactly like a regular store for the buyer!
