Yes, indeed I saw quite a lot merchants that don't want to deal with running nodes, liquidity etc. Even if you explain them that exactly for that Bitcoin was created (skip the intermediaries), they are still not focused on being financial sovereign, as you said are more interested into just taking another form of payment, like another paypal.
It takes time until we will change the fiat mentality, but yea, slowly with good education maybe we will get through.
I am still inclined to see more LSP offering simple solutions for merchants and in the same way they can keep some kind of sovereignty.
That's why I posted this here, I hope that more other smart guys will create such services: offer direct liquidity to merchant nodes, through a simple "pipe".
