Last I heard him talk at one conference, he was talking about making a Liberland app, that's Uber, AirBnB and ebay in one app, using smart contracts on blockchain. And it somehow connects to Liberland.
So yep, I don't see this as a serious attempt.
Edit: here is the app, I have no idea what is it actually doing.
