I don't have access to coinbase purchases, so this is interesting to me and to everyone outside coinbase enabled regions. A lot of people see crypto as a stock exchange thing, too, so it is like a gift card when used by the less knowledgeable. Sellers on this kind of site also greatly benefit from it.

This will be top of the line for me once they get ETH/LTC going.

I won't use any place that asks for KYC unless I can physically present it in the real world. I don't even consider huge players like Coinbase to be reputable. You would not show your private keys to anyone and your identity is the most important private key of all.
