Yup.

My hope is that eventually the "fast ring, slow ring, adjacent ring" system of the EU becomes a thing. I then imagine BeNeLux, Sweden, Denmark, Finland, maybe Czechia entering that fast ring. And as they synchronize their business and tax laws and capital markets, it'll show such an acceleration of growth that almost immediately more EU countries will want to go in on it. The nice thing is that because the "fast ring" would be more of a gentleman's agreement than a true EU institution, it wouldn't be bogged down.

The only hair in the soup I see for the start is that Denmark and Sweden would have to join the Euro, but their currencies are already effectively pegged to it anyway.
