I do. But I am not seeing using monero for large transaction. In my case it would be always less than 500 usd, like some HW wallets or vpn subsciptions type of thing. I am not complete ignorant on the potential of using XMR to buy of sell BTC on places like Bisq, but for my own use I have no need for it and would prefer to use some coinjoin service. 
I am not saying that you are not right. If I was a darknet guy looking to use the markets there, I guess monero would be my choice. But that would be the only case I see for myself.
