1) Monero is really easy to use. You just send a transaction and you're done. The UX/UI of Cake Wallet, Unstoppable, or Stack Wallet is very straightforward.

2) You don't have to trust XMRBazaar at all, because they don’t hold your XMR. Trading happens directly between the buyer and the seller.

3) "So little demand" - that was funny to read, considering that no other cryptocurrency has a marketplace like this.
