I wouldnt advocate for a return of BW - but the one core aspect of what it aimed to achieve, namely global stability, can I believe be achieved without the free option call on society you describe as essential for having globalised finance. Keynes' version of BW would have involved a central clearing house of sorts between countries that would nullify the negative effects of unbounded capital flows by using a common currency. I dont remember the exact details but the big wig at the IMF and the Chinese central bank seemed pretty pro this idea.
"And no, your understanding of the financial crisis is not correct. Ireland socialised losses during the GFC, before the Euro crisis..." Well no. The reason they socialised losses has nothing to do with some inherent requirement to make finance work but because the Euro is a dumb idea as it doesnt allow countries to run a deficit (unless youre Italy/France and too big to kick out) so the only solution to paying off debts is austerity. The reason they had to socialise losses was a faustian bargain also offered to the greeks - basically you socialise our private bank's losses (take out an additional loans) else we switch off your banks and you're dead. Only cutting spending in a downturn is stupid and only makes the debt/gdp ratio worse but first rule of politics is never let facts get in a way of a beautiful theory (austerity)
" the reason we came here is because there is no other choice. You cannot control speculative forces and have a productive economy, it is one or the other." - no. Thats a huge leap to make and has little to no evidence to support the claim. The reason lots of Euro countries socialised losses is not because its a universal law like gravity but due to political expedience. Fundamentally its just unfair to privatise profits and socialise losses.
Sorry I cant comment on the Danes! I'll have a read up
