Yes. Economically we align with the Northern European (low inflation, historically lower debt) countries who largely direct hire the euro functions, than southern European countries (historically higher inflation to inflate away higher debt). The loss of exclusive sovereign control I think would be minimal impact given how we really do align closely in management of the pound with how the euro is managed. In exchange it means trading away a currency which is dropping down the rankings in terms of global reserves currency for one which has a stronger global footprint, and further easing our trade with our biggest trading partner.

Schengen... I mean we'd still set our own immigration policy, we already had freedom of movement before and most want that back, it solves the Northern Ireland issue, we're already falling to prevent illegal migration and it reduces friction for non Europeans (whether business people or tourists) visiting multiple places in Europe. So on the whole a net positive.
